Four months ago Changpeng “CZ” Zhao was incarcerated in a Federal Prison in California. Fast forward to yesterday, it felt like he had never left. the scene.

As a billionaire - 60 times over - CZ sounded less like a crypto evangelist and more like a systems engineer. Speaking in Davos, the former Binance chief laid out a vision in which artificial intelligence quietly does the buying - and crypto quietly does the paying.

The premise is not radical. As AI agents begin to act autonomously - booking services, allocating capital, purchasing data or compute - they will need a form of money that works without banks, borders or business hours. According to CZ, crypto is simply the most practical candidate. It is programmable, globally native, and designed for software rather than shoppers.

Importantly, CZ did not pretend this future has already arrived. Crypto is still rarely used at the checkout. Outside conferences, few people pay for lunch in stablecoins. But that, he suggested, misses where the real progress is happening.

The shift underway is infrastructural. Consumers pay with cards. Merchants receive fiat. Behind the scenes, blockchains increasingly handle settlement, liquidity and reconciliation. Crypto, in other words, is becoming plumbing. Invisible, unglamorous - and indispensable.

This framing matters. Crypto’s loudest critics often attack its failure as a consumer payment method, while its loudest supporters insist adoption is imminent. Both may be wrong. The more plausible outcome is that crypto succeeds precisely by staying out of sight.

CZ placed this payments evolution alongside two other forces: AI adoption and asset tokenisation. Together, they point to a more automated economy, where machines transact with machines at speeds and scales human systems cannot manage.

If that world arrives, it is unlikely to run on card networks designed in the 20th century. Crypto may still be early. But money built for software looks better suited to a software-driven economy.

Crypto exchanges have spent an era optimising regulatory arbitrage. Yesterday, one did the opposite. And it worked.

BitGo’s IPO was not just a listing; it was a stress test. And, awkwardly for many watching from the sidelines, it passed. Strong demand and a confident price told a simple story: public markets are willing to buy crypto businesses - just not any crypto business.

This is why the debut matters. It shifts power. For years, private capital indulged grand narratives, light governance and identical business models. Public investors do not. They ask dull questions about margins, controls and survivability. BitGo answered them. Others are now queuing to try.

Expect a wave of ambition. Exchanges and platforms long rumoured to be “IPO-ready” will rush forward, keen to frame today as proof that the door is open. They are half right. The door is open - but it leads into a very small room.

The problem is arithmetic. Too many exchanges chase the same pools of liquidity, rely on the same volatile trading fees, and promise whimsical differentiation that disappears in a bear market. Public markets tolerate competition; they do not tolerate redundancy. There is little appetite for funding six versions of the same casino.

BitGo succeeded because it sells picks and shovels, not dreams. Custody earns fees whether traders are euphoric or bored. That steadiness is scarce in crypto - and increasingly fashionable.

The coming year will be revealing. Some firms will make it through the scrutiny. Many will not.

BitGo’s IPO was big news not because it crowned a winner, but because it changed the rules of the game. Crypto is no longer arguing with itself. It is being judged against traditional finance and markets, as ever, are unsentimental.

Headlines would usually have an “a” rather than a second “e”, but when stablecoin firms are looking to buy British steelworks, people notice.

That, at least, is the implication of EIG Global Trust, a self-described stablecoin fund, is buying Speciality Steel UK. For Britain, the detail matters less than the direction of travel. Crypto capital is edging out of the digital realm and into the hardest end of the real economy.

This is not as strange as it sounds. Stablecoin firms sit atop pools of capital that need yield, legitimacy and political cover. Buying - or at least financing - traditional industry offers all three. Factories anchor balance sheets, generate cashflows regulators can understand, and provide a useful answer when asked what, exactly, a digital token is for.

For the UK, the attraction cuts both ways. Britain has spent much of the past decade losing industrial capacity while proclaiming enthusiasm for financial innovation. Steel, now deemed “strategic” again, has become too sensitive to fail quietly. If new capital keeps furnaces running and workers paid, ministers will listen - even if the money arrives wrapped in blockchain technology.

Yet this marriage is uneasy. Stablecoins promise certainty; heavy industry delivers volatility. Prices swing, costs bite and politics intrudes. Digital collateral is only as solid as the institutions standing behind it, and Westminster will be wary of swapping one opaque ownership structure for another.

The broader point is that crypto is growing up. To survive, it must attach itself to things governments value: jobs, assets and national capability. Britain, short of capital but rich in legacy industry, is an obvious testing ground.

Whether this ends in revival or disappointment will depend on something unfashionable in both crypto and steel: execution. In the real economy, credibility is not smelted. It is earned, slowly, in pounds and pay packets.

Prices are steady, conviction is not, and the market is waiting to be reminded what it’s meant to care about.
