Crypto, Bitcoin, and the long fight over the rulebook

Bitcoin began as an experiment in money without banks. Seventeen years later it trades through regulated funds, stablecoins carry dollars across borders, and regulators in Washington, Brussels, and beyond are still arguing over the most basic question: what is a crypto asset, legally?

Key facts

  • Bitcoin was introduced in a 2008 white paper and began operating in 2009 it runs on a decentralised ledger, has no issuer and no central bank, and its supply is capped by its own code, which is why regulators struggle to fit it into existing categories. Bitcoin white paper; Reuters
  • The United States approved spot Bitcoin exchange-traded funds in January 2024 the decision let ordinary investors buy Bitcoin exposure through regulated funds, and it marked the asset's arrival in mainstream American finance. US Securities and Exchange Commission
  • The European Union adopted the Markets in Crypto-Assets Regulation, known as MiCA MiCA, adopted in 2023 and fully applied from the end of 2024, sets licensing rules for crypto issuers and service providers across the bloc. European Parliament; European Commission
  • Stablecoins have become the workhorse of crypto payments dollar-linked tokens are used to move value between exchanges and across borders, which is why stablecoin reserves and redemption rights are now the focus of new laws. Bank for International Settlements; Reuters
  • The collapses of 2022 reshaped the debate the failures of Terra and FTX in 2022 wiped out large sums for customers and pushed regulators toward custody, disclosure, and consumer-protection rules. Reuters; US Department of Justice

Crypto began with a provocation: money that no government and no bank could control. The provocation worked. What followed was stranger than the founders expected. The asset they built to escape the financial system now trades inside it, through regulated funds, on regulated exchanges, under rules written by the same institutions it was meant to bypass. The revolution was absorbed. The argument about what it means is still running.

The core of that argument is classification. Is Bitcoin a commodity, a security, a currency, or something new that needs its own category? The answer changes everything: which regulator has jurisdiction, what disclosures apply, how it is taxed, and whether a product built on it can be sold to the public. Different countries have answered differently, and within the United States different agencies have answered differently at different times. The result is a global market that is unified in price and fragmented in law.

Bitcoin grows up, uneasily

Bitcoin's journey from white paper to Wall Street is the industry's founding myth and its most consequential fact. The network has operated continuously since 2009, surviving exchange hacks, bans, crashes, and obituaries. Its supply is fixed by code, its ledger is public, and no single party can change its rules unilaterally. Those properties attracted a constituency that valued censorship resistance above all, and they also attracted speculators, because an asset with a fixed supply and rising demand moves violently in both directions.

The arrival of spot Bitcoin exchange-traded funds in the United States in January 2024 changed the buyer base. Pension funds, wealth managers, and ordinary savers could now hold Bitcoin exposure through familiar, regulated products. Trading volumes and institutional custody followed. Supporters called it legitimisation. Critics called it capture: the asset built to escape Wall Street now depends on Wall Street for much of its price. Both are partly right. Bitcoin's network remains decentralised. Its market is increasingly intermediated, and intermediation brings the regulators with it.

The tax and accounting treatment is still unsettled in many jurisdictions. Some countries treat Bitcoin as property, some as a financial asset, some as a currency for specific purposes. The differences matter for ordinary holders, who may face different obligations for the same transaction depending on where they live. The industry has lobbied for clarity for years. Legislators have discovered that clarity requires choosing a category, and choosing a category creates winners and losers. That is why the lobbying continues.

Stablecoins: the quiet revolution

While Bitcoin argued about ideology, stablecoins got to work. Dollar-linked tokens are used to move value between exchanges, to settle trades outside banking hours, and to send money across borders without correspondent banks. For traders, they are a parking place. For people in countries with volatile currencies or capital controls, they are sometimes a dollar account in a phone. Their growth has made them the most systemically important corner of crypto, and the corner regulators now watch most closely.

The regulatory question for stablecoins is concrete: what backs the token, who holds the reserves, and can holders redeem at par, in full, on demand? The failures and panics of the last cycle taught the same lesson as every bank run in history: a promise to hold a dollar is only as good as the assets behind it and the speed of redemption. New laws in the United States, Europe, and elsewhere have therefore focused on reserve quality, audits, and redemption rights. The details differ, but the direction is the same: stablecoins are being treated as money-like, and money-like things get regulated like money.

The deeper question is who issues the money. Banks, licensed non-banks, and in some proposals the state itself through central bank digital currencies. Central banks in China, Europe, and elsewhere have studied or piloted digital currencies, while the United States has debated the idea without launching one. The politics are sharp: a state digital currency could widen access to payments, and it could also widen state surveillance of payments. The debate is really about the same question crypto started with, who controls the ledger, now asked with the state's full weight behind it.

After the crashes: custody, disclosure, and trust

The collapses of 2022 are the industry's scar tissue. Terra, an algorithmic stablecoin, lost its peg and wiped out tens of billions of dollars in value. FTX, one of the largest exchanges, collapsed amid fraud allegations, and its founder was later convicted. Customers who believed their funds were safe discovered that they were unsecured creditors in a bankruptcy. The lesson, for regulators and for users, was that the risks were not in the cryptography. They were in the companies.

The regulatory response has therefore focused on the companies: segregation of customer funds, custody rules, disclosure of conflicts, and licensing for exchanges and custodians. The European Union's MiCA is the most complete version of this approach, creating a single licensing regime across member states. In the United States, enforcement actions by the Securities and Exchange Commission and other agencies have filled the gap left by Congress, a strategy the industry calls regulation by enforcement and the agencies call the law doing its job. Both sides agree on one thing: the era of the unregulated exchange is over in the major markets.

There is a counterargument the industry makes with some force. Heavy licensing, it says, pushes activity offshore, to jurisdictions with weaker rules, where the same risks reappear beyond the reach of the regulators who pushed them away. The evidence is mixed. Some activity has moved. But the largest flows still run through the largest, most regulated venues, because that is where the customers and the liquidity are. Regulation has not killed crypto. It has concentrated it, in the places that could afford to comply.

Western lens

Western coverage reads crypto as a market-structure story. The American telling centres on the SEC, the courts, and Congress, and on the fight over whether tokens are securities. The European telling centres on MiCA, and on the claim that a single rulebook across a large market is worth the compliance cost. Both tellings share an assumption: the technology is here to stay, the question is the wrapper, and the wrapper is a political choice.

The Western lens is also the most attentive to investor protection, because the losses of 2022 fell on Western retail investors in large numbers. In this telling, custody and disclosure are not technicalities. They are the difference between a market and a trap. The industry's complaint about enforcement is heard, but it is heard after the losses, and the losses set the tone.

Eastern lens

Eastern coverage reads crypto as a sovereignty story. China banned crypto trading and mining while building its own digital currency and its own blockchain applications, a combination that looks contradictory until it is read as control: the technology is welcome, the unsupervised money is not. Other Asian jurisdictions have taken different paths, from licensing hubs to cautious experiments, but the shared instinct is that money is too strategic to be left to an unregulated network.

The Eastern lens also notes that the geography of crypto has shifted east before. Mining, trading, and development have all migrated in waves, following cheap power, friendly rules, and deep pools of retail demand. In this telling, the Western rulebook will not decide where crypto lives. Energy prices, capital controls, and the tolerance of regulators in Asia and the Gulf will decide it, as they have before.

Global South lens

Global South coverage reads crypto as a payments story. For people in countries with high inflation, expensive remittances, or restricted dollar access, a dollar-linked token on a phone is not a speculation. It is a tool. The fees are lower than a wire transfer, the settlement is faster, and the account cannot be closed by a local branch manager. The Southern lens measures regulation by whether it preserves that tool or prices it out of reach.

The Southern lens is also the most sceptical of the crash narrative. The losses of 2022 were real, but so are the losses from inflation and from exclusion from the dollar system. In this telling, the question is not whether crypto is risky. Everything is risky. The question is who bears the risk and who gets to choose. A rulebook written only for the protection of wealthy investors will miss the point for the people who use these tools because they have no better option.

The consensus

What we agree on
All three blocs agree that crypto is no longer a fringe experiment, that the risks are concentrated in intermediaries rather than in cryptography, and that stablecoins are now the most systemically important corner of the market.
What we don't agree on
We do not agree on what crypto assets legally are, on whether stablecoins are private money or public infrastructure, or on whether regulation should prioritise investor protection, financial stability, monetary sovereignty, or access. The same token reads four ways.
What we know
We know the shape of the new rulebooks: MiCA in Europe, spot Bitcoin funds and stablecoin laws in the United States, and the Chinese combination of bans and a state digital currency. We know the 2022 collapses changed the politics permanently.
What we don't know yet
We do not know whether a comprehensive American crypto statute will ever pass, whether stablecoins will be issued mainly by banks or by technology firms, or whether central bank digital currencies will be widely adopted or quietly shelved.
What we expect
We expect the market to keep concentrating in regulated venues, and the next fight to be over tokenised real-world assets: bonds, funds, and property recorded on blockchains. Crypto's second act may be less about new money than about new plumbing for old money.
