The titans of finance are increasingly driving a space that, to many, was designed to put them out of business.

If you were paying attention back then, you don't need to be told this, but for those who were not: Late October 2008 was an incredibly ugly time in money, markets and finance.

Major firms, most famously Lehman Brothers, had just collapsed or required bailouts. Many others were teetering, and the stock market was tanking. Governments and central banks were trying to contain the catastrophe. And I wasn't sleeping well, tangled up in covering the carnage at Bloomberg News.

Oct. 31, 2008, is also when the Bitcoin white paper came out – now 15 years ago to the day. Ensconced in traditional finance, I didn't notice the cryptocurrency revolution had begun, nor had the rest of what we now call TradFi; the financial system appeared to be burning down, after all – we were busy.

Satoshi Nakamoto's paper didn't explicitly say: The world needs a peer-to-peer system to move money around to replace Wall Street giants because they can't be trusted, they're falling apart, etc. But that was the vibe as folks picked up on the idea and made the Bitcoin blockchain and bitcoin [BTC] the cryptocurrency real.

Bitcoin got switched on, BTC started getting mined and stuff started happening – small stuff at first. Pizzas were purchased. A website morphed from a place to swap Magic: The Gathering cards to a giant crypto exchange – and then got massively hacked. Other cryptocurrencies debuted, expanding what blockchains could do. Crypto prices soared – like, really soared – as idealists who embraced the idea of decentralization and cutting out middlemen in finance harnessed Satoshi's ideas, made them real and extended them. (More than a few charlatans got involved as well.)

Wall Street and the rest of TradFi started paying attention – trying to move conventional financial operations onto blockchains and trading "digital assets," their genteel term for cryptocurrencies.

Today, we find ourselves at an ironic moment. These titans of finance are increasingly driving a space that, to many, was designed to put them out of business.

Take, for instance, the story of the moment (excluding Sam Bankman-Fried's ongoing criminal fraud trial). Giddiness over BlackRock (the biggest asset manager in the world) and some of its peers trying to list bitcoin ETFs in the U.S. pushed up bitcoin's price last week, a bet that these easy-to-trade products will bring a flood of investment into BTC. BlackRock and other ETF providers look poised to be – assuming regulators permit these products, and there are reasons to think they'll have to – the new bitcoin whales.

Also, CME Group, owner of the Chicago Mercantile Exchange, is close to overtaking Binance as the largest crypto derivatives exchange in the world. (CME's product is a cash-settled futures contract, essentially a side bet on bitcoin's price; no BTC changes hands). In other words, a business with roots in the 19th century and agricultural commodities like corn and pork bellies, and one of the key spots in all of traditional finance, is a major player in crypto trading.

That said, this is less about how much of the total BTC stash that Wall Street holds. Finance people are increasingly taking over the story – at least to the mainstream – around bitcoin, to an extent that is noteworthy.

What does TradFi muscling its way to the front of the pack mean for crypto?

First, an asterisk: Bitcoin ETFs and crypto derivatives trading (much of it involving BTC) don't mean finance bros are swallowing all of crypto. Bitcoin is not all of crypto – though its market capitalization as a percentage of the whole crypto market is at an unusually high level above 50%.

There are the myriad blockchains like Ethereum and its associated layer-2 networks such as Polygon that run smart contracts – software designed to power various financial and other applications – and that have their own tradable tokens.

That's a whole largely decentralized realm (in aspiration, if not always in practice) that, even to some in TradFi, represents a way to replace conventional ways of doing finance with blockchain-powered versions. That fits broadly with Satoshi's peer-to-peer vision, even if some of the folks that have adopted this mindset collect Wall Street-sized paychecks.

Which brings us back to the irony. Whether bitcoin and crypto folks like it or not, TradFi is coming/is already here – though the degree of their involvement will hinge on regulators' desires, and they're clearly not psyched, judging, for instance, from the actions of the U.S. Securities and Exchange Commission and banking agencies.

Crypto will still have its crypto-y moments, like last week when the price of a totally normal token called HarryPotterObamaSonic10Inu zoomed higher.

"We have proposed a system for electronic transactions without relying on trust," Satoshi wrote 15 years ago.

After Sam Bankman-Fried, Do Kwon and Alex Mashinsky showed what can happen when you trust crypto natives, are users prepared to trust different crypto shepherds? Or will they finally ditch the shepherds, as Satoshi might have hoped?
