There are some very good reasons why risk averse potential new crypto investors may not want to jump in just yet. This guide highlights the problems, risks and where cryptocurrency may be headed. Most importantly investors should educate themselves as much as possible in order to make the best decisions for their particular situation.

Understand Cryptocurrency, but Don’t Invest in It

Cryptocurrency is on everyone’s lips, but it should be in no one’s virtual pockets. An overhyped form of imaginary value storage, it has all the disadvantages of cash, suffers from all the volatility of an overhyped penny stock, and consumes more power than a mid-sized European nation. Although it has been vaunted as untraceable, anonymous, and beyond the reach of governments, none of that is true. Law enforcement agencies have used cryptocurrency to take down crime rings, stop people from exchanging child sexual abuse material, and seize massive amounts of Bitcoin and other currencies.

At one point, I thought cryptocurrency might be among the most exciting and important innovations in technology and finance. It felt as though it had a transformative power in transcending national boundaries, providing a measure of personal independence outside of that offered even in democratically run countries, and disconnecting value and ownership from greedy, predatory, and sometimes corrupt financial institutions.

Over several years, my thinking has evolved to a provisionally cynical position. None of the promises and benefits of cryptocurrency have materialized, as I’ll discuss. Instead, the field has devolved to hype and scams, with the most avid participants—whether fraudsters or true believers—just trying to get as many people as possible to pump real money into digital currency. The phrase “digital Ponzi scheme” crops up a lot.

My overriding advice right now is “Don’t buy cryptocurrency.” No existing cryptocurrency systems provide investing, hedging, or other financial benefits worth engaging with compared to existing financial instruments and markets.

But I say I’m “provisionally cynical” because, despite all that is wrong with the current systems, I urge you to learn as much as you can about cryptocurrency’s underlying principles. Some portion of what we see today will migrate into mainstream finance. That will include activities as broad as sending money to a friend, making certain retail and online purchases, investing in stocks, raising money for projects, and even buying a house. All of these could be wrapped up in immutable, verifiable, transaction records.

It might seem contradictory to say you should avoid engaging in cryptocurrency while becoming a student of it. But that could apply to many dangerous or risky endeavors you want to learn more about safely.​​

Within a few years, more than one government will issue an official form of cryptocurrency, likely including the United States; China is already underway with a digital renminbi. In addition to financial records that are currently managed by government entities like county clerks, permanent ledgers will appear that record details of sales, purchases, and other exchanges of value that require an auditable record.

Private companies, non-profit organizations, and government bodies will likely create ways to participate in decision-making by establishing a cryptographically verifiable stake of value that also gives you voting rights or other involvement in governance. This is akin to stock ownership but with fewer intermediaries preventing you from exercising your opinion.

None of the above is techno-futurism or hype. It all exists today in some form, albeit in examples that are often shaky, unreliable, mismanaged, fraudulent, or intended for Big Brother-like oversight. Bitcoin may eventually fade away—much like once-popular technologies like Gopher and FTP did—but cryptocurrency will survive. A massive percentage of today’s transactions already occur electronically but in such a haphazard and unverifiable way that we need something better.

We’re migrating to a place in which people need to differentiate between public, speculative projects that are far too risky—or simply corrupt from the start—and valid projects that will be based on low-carbon, reasonably scalable private and governmental blockchains used for discrete purposes.

(I learned a lot of the nitty-gritty about cryptocurrency when researching and revising my book, Take Control of Cryptocurrency, which delves into similar topics at greater length: how to understand cryptocurrency without advising you to invest in it.)

Understanding Cryptocurrency Basics

I constantly wrestle with how to explain cryptocurrency to the uninitiated because it involves aspects that cross the boundaries of other kinds of financial instruments, like cash, debit cards, and stocks, as well as those that have no analog in everyday life..

Here’s a gloss on how cryptocurrency is like—and unlike—things we all know:

  • Paper currency: Each cryptocurrency unit is uniquely numbered like paper money. It can pass hands without using a financial institution. The unit value is denominated as part of its nature. Transactions are quasi-anonymous: it’s hard, but not impossible, to trace the flow of value from one party to the next, at least for law enforcement when large amounts are involved. But cryptocurrency isn’t like paper money because you have to pass it through an online system. Plus, some cryptocurrencies, like Bitcoin, are highly volatile, unlike cash in most modern societies.
  • Debit-card transaction: When you use a cryptocurrency, you’re always sending money; there’s no invoice, billing, or debiting process. This makes it somewhat like using a debit card—an electronic transaction that comes out of your stored value (your savings) held on a ledger somewhere (your bank’s records) that’s sent in a way the recipient can verify as legitimate. Yet, cryptocurrency’s “ledger” isn’t stored in a central location like your bank—it’s a distributed consensus that agrees on what transactions have occurred, so there’s no one to complain to if something goes wrong.
  • Stock ownership: In many ways, cryptocurrencies are like stocks. Owning shares in a company lets you ride the tide of a combination of the firm’s real value and sentiment about its future earnings. For a company in turbulent times or around which rumors swirl, the price of shares can zigzag up and down. The stock can be exchanged for currency through intermediaries and vice versa. Cryptocurrency shares the volatility of stocks but doesn’t reflect any underlying fundamentals, just market perception. If it’s like stock, no “company” exists whose value and performance are reflected in the “shares.”
  • A password: At its heart, cryptocurrency relies on knowing secrets. Proving ownership or spending any chunk of crypto coin requires an encryption key that only you possess. But unlike a password used to unlock a computer or online account, you don’t gain access to anything with the key—you only use it for proof. All your ownership comes from that proof.

So with that in mind, what is cryptocurrency itself? Although it might take some advanced study to truly understand it, I can explain the basics in a few sentences. Cryptocurrency is a financial instrument that uses cryptography instead of other methods (like physical possession or traditional financial institution database entries) to verify ownership. When you purchase cryptocurrency, the transaction is written into a permanent, distributed ledger—a blockchain—that uses cryptographic algorithms to render the records permanent, unchangeable, public, and verifiable by any party.

As fully decentralized systems, cryptocurrencies don’t need a government or other single entity to issue units. Instead, cryptocurrencies rely on a consensus mechanism that lets participants bypass trusting any individual or organization. The blockchain contains the “truth”—you de facto don’t own that cryptocurrency if your record of ownership isn’t in the ledger, if you can’t produce a private encryption key related to your ownership (the classic “lost key” scenario), or if the transaction can’t be verified. It’s like having a bank account with a balance in it you can’t access—ever. Because there’s no central authority managing a cryptocurrency, there’s no one to complain to in the way you might dispute a charge with your credit card company or force a bank to release your savings account through a court action.

How Bitcoin Works

Here are the four major parts of Bitcoin, the highest valued cryptocurrency by far:

  • A group of people (miners) voluntarily compete over short periods of time, about ten minutes, to solve a mathematical needle-in-the-haystack puzzle. The miner who solves the puzzle first is the winner and receives a chunk of Bitcoin. Only one miner is successful for each block; all other effort is discarded. The puzzle resets and the contest begins again. Most mining is done by a handful of heavily invested mining companies.
  • A network of peer-to-peer, independently operated software servers (nodes) exchange information about transactions waiting to be recorded, recently solved puzzles, and the state of the network and system.
  • Sets of transactions are tied together cryptographically through mining (blocks). A miner creates a block when they solve the mining puzzle and broadcast their solution to nodes.
  • An immutable ledger of all completed transactions grows by one block of new entries each time the mining puzzle is solved and accepted by nodes (blockchain).

One way to understand how Bitcoin works in practice is to compare a Bitcoin payment with a purchase made using a chip-based card or mobile payment system like Apple Pay. Here’s how that card-based transaction proceeds:

  • When prompted to pay (either in person or via mobile payment in a browser or app), your card or mobile device performs a cryptographic handshake across a network to validate the payment and create a unique set of information that the payment network accepts. Your possession of the card (in person) or a biometric approval (like Face ID) makes the transaction legitimate.
  • The merchant receives a digital acknowledgment that a payment was made.
  • In a ledger maintained by the payment system, the transaction amount is debited from your record. It’s either applied as a charge on a credit card ledger maintained by your credit card issuer or it’s debited against your bank account and transferred as an electronic record through the payment network as a credit on the seller’s merchant account.
  • Fees are collected in various ways across the system, typically from the merchant, and paid out in various amounts to the payment processor, payment network (like Visa or Discover), and merchant’s bank.
  • If your payment is later declined, the merchant can complain to the payment network. If you have a problem with your purchase, you may be able to have the charge or debit reversed and refunded to you through your bank or credit card issuer.

With a Bitcoin payment, the process works similarly in total, but the actual set of actions is quite different:

  • Get someone’s Bitcoin address. (Even ordinary people may have many.) It may be provided in a number of ways, including plain text or a QR code.
  • Send them money via wallet software. The transaction requires a fee to encourage a miner to consider including your transaction as part of their puzzle block. The wallet software essentially stores the encryption secrets you need to create a properly formatted transaction that proves your ownership to send a value to an address, and uploads that transaction to a node.
  • The node broadcasts your transaction to other nodes in the network. Since it’s a peer-to-peer network, nodes are constantly receiving and broadcasting transactions.
  • The transaction floats in a pool of all outstanding transactions until various miners’ software decides the fee is worth it to include in their attempt to solve the puzzle.
  • A miner whose transaction payload includes your transaction solves the puzzle and distributes a block with the transaction baked in.
  • Other nodes independently validate that block and add it to their copy of the blockchain.
  • The recipient can validate that the transaction has been added to the blockchain by examining recent entries on the blockchain. Wallet software automates this.

New units of Bitcoin can be created only by miners, and only a limited amount of Bitcoin can ever be created. That amount halves about every four years. The current reward is 6.25 Bitcoin per block. You can divide Bitcoin units down to tiny units called Satoshis, which are one-hundred-billionth of a Bitcoin. For example, $5 is roughly equivalent to 0.000124 Bitcoin or 12453.05 Satoshis.

Miners can then use those Bitcoin units to pay others in Bitcoin or cash out through cryptocurrency exchanges. These exchanges provide crucial liquidity for Bitcoin markets. Without parties willing to trade Bitcoin for other cryptocurrencies and for government currency, Bitcoin would be an entirely closed system. Exchanges bear the risk of holding and trading cryptocurrency. They have to determine what price they will pay or charge for Bitcoin based on their own algorithms and monitoring prices paid at other exchanges. Cryptocurrency exchanges are similar to international currency exchanges, earning a fee as part of these conversions. When a lot of people want to buy Bitcoin, the price may climb rapidly, but there’s a lot of Bitcoin to sell. Conversely, when people want dollars for Bitcoin, the price can plummet as exchanges hold relatively limited amounts of hard currency compared to conventional banks or central government banks.

The Bitcoin algorithm provides a mechanism to keep block production on a cadence of about one every 10 minutes. That rate prevents the peer-to-peer network from being overwhelmed while also providing time for transactions to “cure”—to be in the blockchain long enough that they are securely locked in place. (This helps protect against the 51% attack described below under immutability.) As miners add computational capacity, the Bitcoin system resets the difficulty of the puzzle they have to solve every few days. The additional computational speed is effectively offset by the difficulty factor, resetting it back to the 10-minute cadence. This method of requiring some weighted amount of effort is called proof-of-work, and it’s the basis of trust as it can’t be faked. Only hard work can solve the puzzle—there’s no shortcut.

Bitcoin mining difficulty over time
Difficulty is a factor that started at 1 in 2009.

Constantly adjusted difficulty requires miners to invest in faster equipment lest their competitors begin to earn more rewards. This strategy burns more and more power in a Red Queen’s race to get almost nowhere: the outcome is the same, but the electrical consumption and environmental cost increase in step with the difficulty. Mining makes economic sense only as long as the miners’ cost of equipment, facilities, and power remains on average lower than the value of the Bitcoin they earn as rewards.

Occasionally a blip occurs—such as a sudden drop in Bitcoin’s price or Chinese authorities banning mining—that reduces the profitability and takes mining capacity offline. In those cases, the difficulty resets to a lower level. Generally, the difficulty is an ever-rising line.

Ethereum and NFTs

Bitcoin’s younger sibling is Ethereum (its currency is Ether). One Ether is worth about 8% of a single Bitcoin, and cryptocurrency exchanges value the full market value of the outstanding Ether at about half that of Bitcoin. Unlike Bitcoin, Ethereum wasn’t created as a replacement for cash, nor does it have a limit on the maximum amount of Ether that can be mined. The Ethereum network can perform simple transfers of value, and that’s its most frequent use. But its power lies in smart contracts, network-based programs that run when they receive an input. They’re like tiny virtual software containers. Smart contracts can allow complicated rules for taking an incoming payment and splitting it up, but they can also be used for more sophisticated purposes. That includes decentralized autonomous organizations (DAOs), groups that set up smart contracts that define ownership, voting, and the consequences of votes—a nice idea, but such groups exist largely outside existing regulatory structures except when they fall afoul of fraud, attacks, and mismanagement. Ethereum also supports distributed apps (dApps), which remain in an experimental stage: they allow the use of the Ethereum network as a general-purpose distributed computer.

Ethereum also enabled one more element you should know about because they’ve been so omnipresent in the media: NFTs, or non-fungible tokens. NFTs are also entries on a blockchain but are formatted in a special manner that allows them to be created without an associated currency-style value. An NFT is effectively a serialized token with its uniqueness established by residing on the blockchain—like a signed baseball card or a ticket to a concert.

To explain, a fungible asset is one that’s identical to all others of its class: any dollar in one bank account is the same as any dollar in another. In contrast, a non-fungible item can’t be exchanged like for like. In the real world, non-fungible items include works of art, real estate, and collectibles.

An NFT doesn’t confer ownership of an underlying asset, like a copyright, licensing permission, or possession of a physical object. It’s just a pointer that points to a URL. Once set, that URL can never be changed because NFTs are immutable. This is why people joke about “right-clicking to steal” NFTs: most NFTs point to images hosted on publicly available Web pages that can be downloaded locally by right-clicking and choosing Save Image As.

Bitcoin can’t host NFTs, because it’s not “programmable,” so many NFTs are based on Ethereum. However, there are also now cryptocurrencies created solely to issue NFTs. As tokens, NFTs can be sold for arbitrary values. They aren’t fixed, like units of cryptocurrency.

The most reported-on use of NFTs is making iterative pictures of ugly graphics, like apes and lions. That’s the least interesting use, however, as NFTs could provide verifiable uniqueness for all sorts of things along with transferable ownership.

With those basics out of the way, let’s look at the myths of cryptocurrency and then see where it’s headed.

The Myths of Cryptocurrency

People who are cryptocurrency advocates or promoters tend to gloss over or ignore its drawbacks. You can hear them and more credulous tech writers recite a litany of cryptocurrency benefits:

  • It’s anonymous.
  • It’s untraceable.
  • It’s decentralized.
  • It’s immutable.
  • Immutability is good.
  • It’s anti-inflationary.
  • It always appreciates in value.
  • Transactions are cheaper than credit cards.
  • It’s removed from governmental control.
  • The environmental problems will be solved.
  • It’s safe.
  • It’s simple.

I could write even more thousands of words explaining why all of those are misguided, false, exaggerations, or require footnotes and provisos. Let’s see if I can instead knock them off in a few paragraphs.

It’s anonymous. It’s untraceable. Cryptocurrency transactions rely on a public blockchain that everyone can see and validate independently. This is part of the basis of decentralized trust: you don’t have to believe anyone; just check the cryptographically consistent record. As a result, you can trace transactions over time as they move between addresses. Companies like Chainalysis specialize in this. It’s better to say that Bitcoin and other major cryptocurrencies are pseudonymous: identity and address are separate things but can be associated. (A few cryptocurrencies, like Monero, offer something much closer to irreversible anonymity, but their transactions are a tiny fraction of all those conducted.)

Tracing crypto transactions

It’s immutable. It’s decentralized. The blockchain is designed to be immutable, but that relies on true decentralization of mining. Any time at least 51% of the computational power across the entire mining network is controlled by a single entity or back-room deal, the chain could be reversed by a few too many blocks depending on the amount of computation. It could allow double-spending, in which units of cryptocurrency appear in a block that becomes invalid, but which the receiving party has already acted on (like releasing a real-world escrow or transferring ownership of a digital asset). Such a cabal could even prevent others from having their transactions written to the blockchain. This isn’t theoretical; it has happened several times.

Many cryptocurrencies and seemingly nearly all NFT projects have a high degree of central ownership: one or a few parties control the entire system and the direction it takes. Even when a larger group of people are involved, a small minority that controls the majority can have effective control. For instance, following a huge DAO meltdown in 2016 that would have cost participants the equivalent at the time of $150 million, the core Ethereum group, the Ethereum Foundation, stepped in to rewrite Ethereum’s rules to annul the theft. This resulted in a hard fork of Ethereum, resulting in the Ethereum Classic spin-off created by those who disagreed with the move. Even with wallets, software that manages ownership and sales, consolidation among vendors can lead to a situation where an immutable entry simply doesn’t appear because the wallet developer blocks it.

Immutability is good. You could argue that in general cases, blockchains are immutable. But is that always good? Immutability is overrated in one sense. When you make a credit card purchase, you have a variety of protections under the rules of the card, the card’s issuing bank, and your state or region or national government. Credit card transactions aren’t immutable, and thus they can be reversed to respond to fraud, misrepresentation, or other reasons. (Banks may hold balances or require reserves to cover reversed transactions.) Cryptocurrency transactions would be immune from such protections.

Also, blockchains can store or point to all sorts of data. Future blockchains may have the spare capacity to encode large amounts of data, such as complete legal contracts, media, and source code of software. So what happens when CSAM, “revenge porn”, deeply personal details, and stolen software are permanently encoded into blockchains? For some categories of harm, the blockchain might be effectively illegal to possess on your computer or even view parts of—it simply hasn’t been adjudicated.

It’s anti-inflationary. It always appreciates in value. At one point, economic/political promoters of cryptocurrency liked to assert that Bitcoin and others would resist inflation. As inflation rises, currencies devalue relative to what they can purchase. Cryptocurrencies were supposed to counter that by having a rising exchange rate with real-world currencies to offset devaluation. It was a tricky point to make in the middle of one of the lowest periods of inflation across established economies in global economic history. And it hasn’t happened as inflation has increased in the last year. Instead, cryptocurrency has generally been so volatile, with huge spikes and drops multiple times since 2019, that it’s hard to draw any conclusion.

Bitcoin and Ethereum vs. inflation

Internally, Bitcoin and Ethereum try to restrict the growth of their basic units. Bitcoin was created with a finite number of coins that can ever be used; Ethereum is unlimited but implemented a change in August 2021 to “burn” (permanently destroy the value of) Ether with every transaction relative to its complexity to prevent the deflationary effect of constant growth of Ether.

Transactions are cheaper than credit cards. A selling point of Bitcoin in its earlier days was that it would cost fractional US cents to carry out a transaction compared to the roughly 3% that credit cards eat up. It would enable micro-transactions, letting you send pennies to pay bloggers and dollars to pay musicians. That didn’t last.

Because Bitcoin and Ethereum can handle only a modest number of transactions per minute, the fee paid to miners becomes a huge component of having transactions written to the blockchain. This pressure caused the cost of Ethereum transactions to rise to tens of dollars in 2021, regardless of the size of the transaction. Bitcoin fees have remained lower but can still average several dollars. (Some attempts to increase the transactions-per-second rate involve layering other blockchains on top of existing cryptocurrencies. However, building a robust infrastructure on top of unstable foundations comes with many risks.)

On top of that, Ethereum has what are called gas fees that are tied to the cost of executing a transaction, since all Ethereum transactions equate to programs that consume computational resources. Complicated smart contracts can require huge amounts of gas compared to a simple value transfer. These gas fees can become astronomical—much higher than the actual amount being transferred. Plus, you can’t accurately predict how much gas a transaction will require. If your wallet transmits the transaction without enough gas, you forfeit the gas fee and your transaction isn’t added to a block. The worst of both worlds! (The workaround is to send too much gas, after which the extra is refunded along with the output of a transaction. Previously, gas used to be paid to miners, but since August 2021 is burned, as noted above.

$201.18 gas fee
The fee to fill out a simple ENS Domain form to update a .eth domain record. The fee is $0. The gas fee? $201.18.

This has resulted in an absurd situation where refunds from a failed collaborative project to buy a copy of the Declaration of Independence cost participants more than their initial contribution. Such scenarios are common.

The environmental problems will be solved. Cryptocurrency remains an environmental disaster of the highest order. Bitcoin burns electricity equivalent to the requirements of a modest-sized European country to no good end: the value per Bitcoin doesn’t match the amount of energy required to mine it. Mining a single Bitcoin could require 1 watt of power or 1 gigawatt of power. For practical purposes, the cost of mining produces an effective ceiling due to capital costs, operating expenses, and power usage. Miners try to stay in the black by mining more Bitcoin than their costs. However, if Bitcoin skyrocketed to ten times its current purchasing power, miners would fight an upward race to find more power wherever they could. The credit card network is millions of times more efficient per transaction and scales incrementally instead of in lockstep as transactions increase—ten times the current volume doesn’t require ten times the current hardware or electrical use, as most of the investment is in basic infrastructure.

Because the vast majority of cryptocurrencies, led by Bitcoin and Ethereum, use algorithms that require particular computations, it’s possible to estimate how many operations are performed per second across the network. Digiconomist uses that and other data to estimate a range of about 80 to 320 terawatt-hours per year of use between Bitcoin and Ethereum. That’s somewhere between the amount of electricity used by Belgium and the UK.

Miners also literally burn through hardware, resulting in shortages of chips used for more productive purposes and a massive flow of e-waste, most of it unrecyclable. Digiconomist estimates Bitcoin mining results in 34 kilotons (70 million pounds) of tossed gear, equivalent to the IT waste of the Netherlands.

Promoters regularly try to explain how cryptocurrency is en route to becoming “greener” in two ways. First, Ethereum may be nearing the end of a multi-year transition to Ethereum 2.0, an energy-efficient algorithm that scales well without a corresponding leap in resources. The new protocol relies on proof-of-stake, which validates new transactions based on people’s ownership of Ether rather than how much computational work they perform.

If Ethereum 2.0 is successful, about which there are grave doubts and major anxieties, it could reduce Ethereum’s energy consumption by 99% or more. Still, even at 100 times more efficient, it remains several orders of magnitude worse than, say, a Visa card charge. Promised years ago, the transition is always just a few months away. In fact, just days ago the latest upcoming target for the transition was pushed to… a few months away.

Many crypto advocates argue that the mining world has a plan—already alleged to be somewhat underway—to transition to renewable resources, such that it will ultimately be emissions neutral. Instead of effectively mining Bitcoin from coal and natural gas, why not tap into solar and wind, or put a geothermal generator on a volcano? These are nice ideas, but the Earth is a closed system: there is no surplus production of renewable power generation equipment or naturally occurring, accessible sources of renewable energy. Skeptics call this greenwashing, in which noble reductions are trumpeted when the reality is much different.

Because only a finite amount of equipment can be made and put into service, any “non-productive use” (burning computation cycles for cryptocurrency) removes capacity from other purposes. Either miners buy a lot of solar and other equipment or output of renewable plants, just as they caused hardware shortages for GPUs and SSDs, forcing other generators to use dirtier power; or they keep using the dirtiest power as the rest of the world moves towards a less destructive approach.

It’s removed from governmental control. Earlier in this story, I noted how governments have become adept at tracing cryptocurrency and, more recently, at reclaiming it. The US Department of Justice seized $3.6 billion (8 February 2022 valuation) of Bitcoin connected to a major 2016 hack of the Bitfinex exchange. That’s the largest such seizure, but dozens of others have occurred, including $34 million from an alleged scammer in Florida by the U.S. government on 4 April, $25 million by the German government on 5 April, and an unclear amount of donations to those involved in occupying downtown Ottawa earlier this year. (Josh Centers wrote an elaborate analysis of crypto as a workaround to governments for his prepping-related publication, Unprepared.)

It’s safe. Advocates would like to tell you that it’s safe to invest in and possess cryptocurrency, but to rebut that point I simply suggest you read through Molly White’s “Web3 is going just great,” site, which is a seemingly endless feed of scams, rug pulls, hot potatoes, phishers, incompetents, and other old-timey frauds and business failures rendered anew. (Rug pulling is raising funds for a project and then taking those funds without delivering on the promises in fairly quick order. A hot potato is a coinage I may have come up with for finding the least savvy person to leave holding the bag—one without any money in it.)

It’s simple. If you’ve read this far, you’ll understand why this claim should elicit hysterical laughter.

Where Cryptocurrency Is Headed

How can I argue cryptocurrency is part of the future of financial systems when I’ve just told you how thoroughly pointless, broken, and fraud-ridden it is? Because it has a number of excellent ideas that could be expressed in more reliable, trustworthy, and useful ways. To achieve these goals, we need new cryptocurrencies that change some of the principles proven false in the idealized initial approaches.

  • First, some elements of centralization could dramatically improve cryptographic-based transactions without putting any or all of it in the hands of governments, all while keeping identity secret without exaggerations about anonymity or privacy. Instead of trusting software developers and cryptocurrency creators—while claiming you trust no one—we would trust other entities that can be better vetted. The notion of complete decentralization was clearly a dream of idealists that, in practice, has proven as problematic as the worst cynics predicted: the control of most cryptocurrencies is in the hands of a few people who have accumulated lots of money. Ditto, anonymity, as I’ve noted throughout this article.
  • Second, any new cryptocurrencies need to provide a way to cap and control transaction fees to keep them predictable and low, a claimed advantage that hasn’t proved to be the case in reality. Imagine a value-transfer system that was far cheaper than the credit card system, which averages around 3% in the US, and other more costly person-to-person and funds-transfer systems. Later cryptocurrency systems that learned from Bitcoin and Ethereum can carry far larger numbers of transactions, reducing pressure and enabling far cheaper transactions.
  • Third, a key goal should be reducing fraud. Existing cryptocurrencies regularly suffer from exploitable weaknesses across the ecosystem—some fundamental in the protocol, some in wallet software, some in smart contracts, and some at consumer crypto-financial websites. For instance, as Cory Doctorow noted of smart contracts, they “don’t just create instability by being too complex to understand and vulnerable to coding errors–they’re also fraud magnets”; being immutable, they can’t be updated and require you to run a buggy program forever. The credit card system isn’t a paragon to compare to: it lost nearly $30 billion to fraud in 2020, a number expected to rise. Because a tightly controlled secret is at the heart of all cryptocurrencies, the possibility to reduce fraud and theft has a high upside for consumers, banks, and businesses.
  • Fourth, a government-regulated cryptocurrency could make trans-border commerce easier without reducing accountability, fraud resistance, and protections against funding terrorism, laundering money, and engaging in financial crime. It’s typically slow and costly to send money between countries (outside of the European Union), particularly for smaller amounts. Economic migrants and cross-border workers may pay roughly 5% to 8% of what they send back to family in remittance fees, for instance, for over half a trillion dollars of transfers.
  • Fifth, a future cryptocurrency could allow an organizational structure in which your stake gives you proportional voting rights in projects that aren’t publicly traded corporations. (Companies tend to have concentrated ownership and even separate classes of voting shares that dilute the effect of individual and small owners.) We can see this in effect already with decentralized autonomous organizations that use smart contracts that combine a purchase with a stake. A DAO ostensibly provides validated voting, a public record, and directly enforceable outcomes. The reality hasn’t matched up with the theory yet, but there might be a role for smart contracts in certain kinds of organizations.

One of the earliest examples of a more regulated, non-volatile, and perhaps government-backed cryptocurrency will likely be a stablecoin. A stablecoin is cryptocurrency pegged to a fiat currency, like the dollar or euro. Existing stablecoins, like Tether’s USD, rely on managers who buy and sell assets to maintain holdings they claim are redeemable on a 1:1 basis between USD and actual US dollars. (Tether’s claims of reserve assets are highly disputed, due to the company having over $80 billion in ostensible outstanding stablecoins; Tether may possess only a fraction of that in cash and short-term liquid securities.)

Current stablecoins don’t have their own blockchain but are built as special kinds of transactions on top of existing cryptocurrency blockchains, making them no better at avoiding underlying issues like environmental devastation and processing speed. Management is centralized at the top layer, as the stablecoin operator has to maintain assets and issue new stablecoin. However, once issued, stablecoin units can be as freely traded without central involvement as any other cryptocurrency.

Governments like the United States already use their own non-cryptographic ledgers to track electronic cash. The U.S. Federal Reserve said that for February 2022, out of $21.8 trillion in cash in the money supply, only about $2.2 trillion—roughly 10%—circulates as notes and coins.

What’s the difference between a US-managed stablecoin and the Federal Reserve’s record of cash? Cryptographic validity and transaction tracing. For some people, the former is highly desirable and the latter something they want to avoid out of principle; for governments, both could be useful. Transaction tracing is a key reason why China is pushing forward with its digital renminbi.

A private or invitation-only blockchain could power a US Treasury stablecoin. Private blockchains in which stakeholders maintain trust internally have become increasingly popular. Given that the US government has never defaulted, it may be able to occupy the role of running a private blockchain to power a US Treasury stablecoin. You could also imagine a consortium of US credit unions given a charter to run a stablecoin to further their mission of extending banking, reducing fees, and providing fair mortgage and lending rates.

That stablecoin might not become available for years for average people or uses. Instead, it might be a way to transfer value securely among institutions, for their own purposes or for consumer and business needs. For instance, imagine buying a house. Instead of escrow, a stablecoin transaction would provide the security that money has changed hands with cryptographic assurance instead of a call or letter from a bank. (Or, for those who remember, a certified check in an obscenely large sum.)

Countries would need to update their laws to deal with widespread use of cryptocurrency. For starters, laws need to change to deal with immutability when so much else about property can be adjudicated: a court might say money has to go from one place to another and enforce that through the banking system, but it would have no power over existing cryptocurrencies.

Yet, every time I need to send money to another person, pay for something online, or receive payment for goods I sell, it’s hard not to imagine that our creaky old financial system would benefit from a modern approach that uses encryption as a component of security and assurance.

It’s hard to say what the future of cryptocurrency will look like. In the meantime, I repeat my advice at the outset: watch and learn, but don’t invest.
