Cryptocurrency was built with a specific issue in mind: That money doesn't need anyone's permission to move. The answer, years later, is complicated.

The crypto market is still technically decentralised. Blockchains still run without central servers. No single government owns Bitcoin.

But look at who holds it, who controls the platforms where most people trade it, who is writing the rules around it, and who gets to decide which tokens survive, and the picture looks a lot less like a financial revolution and a lot more like a reshuffled version of the system it was supposed to replace.

That observation is quiet, gradual, and not usually announced. But it is happening, and it matters, not just for crypto's ideological identity, but for what ordinary people holding digital assets can actually expect from the market going forward.

Crypto Was Built to Be Decentralised — So Why Is Power Becoming Concentrated?

Research published in 2025 on Bitcoin's transaction network from 2009 to 2023 found that Bitcoin has evolved into a highly centralised structure, with high levels of wealth inequality and crystallised power dynamics that could threaten its long-term sustainability.

Separately, academic analysis of major cryptocurrencies, including Bitcoin, Ethereum, Cardano, and Polkadot, found that the top 0.1% of holders control an overwhelming share of each network's wealth, with Cardano's Gini coefficient, a standard inequality measure, sitting at 0.82.

On governance, the numbers are equally stark. In MakerDAO's 2024 Stability Fee vote, the top 1% of token holders cast 85% of all votes. That is not decentralised governance. That is a different kind of oligarchy, one that runs on code instead of boardrooms, but produces the same result: a small group of people making decisions for everyone else.

Meanwhile, US spot Bitcoin and Ethereum exchange-traded funds (ETFs) attracted $21.4 billion in combined flows during 2025 alone, while spot Ethereum ETFs pulled in $9.9 billion, bringing the combined total to approximately $31.3 billion for the year, with BlackRock's iShares Bitcoin Trust (IBIT) accumulating over $50 billion in assets under management within a year of launch.

By year-end, US spot Bitcoin ETFs collectively held over 1.36 million BTC, roughly 7% of the entire circulating supply, in the hands of a handful of institutional custodians.

The Language of Crypto and What It Actually Means Right Now

Decentralisation, in its original meaning, describes a system where no single party holds control, transactions are verified across thousands of independent nodes, and no government, bank, or corporation can freeze, reverse, or censor them.

That principle remains technically intact at the protocol level. The blockchain itself hasn't changed. What has changed is the layer above it. Centralised exchanges (CEXs), platforms like Binance, Coinbase, and Kraken, are where most people actually buy, sell, and hold crypto.

These are private companies with terms of service, the ability to delist tokens, freeze accounts, and apply Know Your Customer (KYC) requirements. When Binance delisted privacy tokens in 2024, affected coins dropped 40% in value within 24 hours. That is centralised power operating inside a decentralised market.

Decentralised finance (DeFi) was supposed to be the answer to CEX dominance, peer-to-peer lending, borrowing, and trading through smart contracts without intermediaries. But even here, governance whales, large holders of governance tokens, have accumulated enough voting power to override community decisions.

The decentralisation is structural; the control is behavioural. ETFs add yet another layer: they give institutional investors exposure to crypto prices without ever touching a wallet, keeping the financial system's existing custodians firmly in the chain.

Who Is Driving the Shift and How

Governments have moved from hostility to structured incorporation. The European Union's Markets in Crypto-Assets (MiCA) framework took full effect in January 2025, creating a regulated environment that favours compliant, institutionally backed projects over independent ones.

The US Congress passed the GENIUS Act on stablecoins in 2025, creating a permissioned framework, not a permissionless one, with designated roles for banks and regulated issuers. China continues to tighten restrictions. The net effect across every jurisdiction is the same: regulation is reshaping crypto in the image of the financial system it was built to escape.

Institutions are accelerating it. MicroStrategy acquired 258,320 BTC in 2024 alone. Corporate treasury allocations to crypto surged past $6.7 billion. BlackRock, the world's largest asset manager, now has a dominant 48.5% share of the Bitcoin ETF market. When these entities move, the market moves with them, ordinary retail investors react to decisions made in boardrooms, not on blockchains.

Ordinary users are completing the picture, often without realising it. Most people never set up a self-custody wallet. They deposit funds on Coinbase or Binance, accept the terms, and hand over their keys in exchange for convenience.

In crypto's foundational logic, that is equivalent to putting your money back in a bank. The phrase the community coined for it, "not your keys, not your coins", describes exactly what most users are choosing to ignore.

Crypto hasn't been captured from the outside. It has been handed over, piece by piece, by the choices of every participant in the market, regulators writing rules, institutions buying leverage, and users choosing ease over sovereignty. The blockchain is still decentralised. The question is whether any of that actually matters anymore.
