The 50 Most Interesting Companies
in Bitcoin's History

What Failed, What Captured Value,
and Where Value Accrues Next

Why So Many Things Failed

Across fifteen-plus years of Bitcoin company formation, the failures cluster around a handful of patterns.

Custody remains the industry's largest challenge. Mt. Gox, QuadrigaCX, and dozens of smaller exchanges lost customer funds because they treated custody as an afterthought, running on single servers with no audits, no segregation of assets, and no real controls. That lesson took years to sink in, and it is now the starting point for every serious infrastructure company: if you hold other people's Bitcoin, custody is the product. The 2026 Coldcard entropy bug drained roughly $116 million from owners who had done everything the industry told them to do, a reminder that custody risk moved rather than disappeared.

Regulatory naivety constrained the second wave. BitInstant, BitMEX, and even Binance built products that attracted enormous demand, then got taken down or reined in because they assumed regulators would not notice or would not act. The consequences followed the same arc each time, with Charlie Shrem going to prison, BitMEX's founders pleading guilty and paying fines, and Binance paying $4.3 billion while CZ stepped down as CEO. The companies that treated compliance as optional eventually learned it was not.

Outright fraud exploited the trust gap. FTX and Celsius did not fail because the technology broke, but because operators abused an industry that still lacked the guardrails of traditional finance. SBF commingled billions in customer deposits, and Alex Mashinsky marketed Celsius as a savings account while making directional bets with depositor funds. These were human failures amplified by the absence of oversight, and the uncomfortable part is that some of the most sophisticated investors in the world, from Sequoia to SoftBank to Ontario Teachers', were fooled right alongside retail depositors.

Narrative without product. Many companies raised enormous sums on a thesis, "we will bank the unbanked," "we will tokenize everything," "we will replace SWIFT," without building something people actually used. The 2017 ICO wave was the clearest version of this, but the pattern persists, with capital flooding into stories rather than into products with real demand. The companies on this list that survived are the ones where the product pulled capital in, not the other way around.

What Actually Captured Value, and Why

The companies that captured durable value share one trait: they became infrastructure that other businesses and institutions rely on.

Exchanges and on-ramps captured the most obvious value. Coinbase's roughly $85 billion IPO was built on a simple insight: someone has to sit between fiat and digital assets, and that seat is extraordinarily valuable. Kraken operated for a decade on modest capital before raising at a multibillion-dollar valuation. Bitstamp was acquired by Robinhood. These companies sit at the front door of the ecosystem and earn a fee on nearly every dollar that enters.

Custody and key management became one of the most defensible categories. BitGo, Anchorage, Fireblocks, and Xapo all understood that institutional capital cannot enter an asset class without institutional-grade custody. Anchorage earned a federal bank charter. Coinbase acquired Xapo's custody business for $55 million. Fireblocks grew into an $8 billion company. When you are the entity institutions trust to hold billions, switching costs become very high.

Mining hardware captured value through physical moats. Bitmain earned $701 million in net profit in a single year by controlling most of the ASIC market, and along with Canaan and MicroBT it captured the most consistent value in mining, because operators have to buy new equipment every cycle regardless of price.

The investment vehicles captured enormous value in their own right. Grayscale's GBTC became a $30 billion-plus vehicle by giving institutions a familiar wrapper for Bitcoin exposure. When the spot Bitcoin ETFs launched in January 2024, BlackRock's IBIT pulled in tens of billions in its first year, the most successful ETF launch in history. Packaging and distributing Bitcoin exposure to traditional investors is a large business on its own.

Where We Think Value Accrues Next

Multi-institution custody is where the durable economics live, and it is only beginning to proliferate. The first generation of custody solved holding Bitcoin safely. The next step is distributing that trust so that no single entity, including the custodian, has unilateral control, which is the model Unchained and Onramp have built. What we find most interesting is what gets built on top of that primitive. As custody extends into API access, white-label offerings, and infrastructure-as-a-service, it becomes a platform other institutions build on rather than a single-brand product, and a growing stack of financial services, lending, treasury, retirement, and payments, will sit on top of it.

Lending and treasury management sit closest to that custody layer. Bitcoin-backed credit, treasury management across both Bitcoin and stablecoins, and full-service products that put the asset to work while it stays in verifiable custody are the businesses we expect to compound, because they earn a spread without asking the client to hand over the coin.

Bitcoin and AI will increasingly be built together. We expect a large share of the next generation of valuable companies to use both, whether that means AI improving how custody, compliance, and operations are run, or software agents that hold and move value natively on Bitcoin and Lightning rails. The bar for what counts as institutional grade rises every quarter, and the teams with real depth in cryptography, financial engineering, and now AI tooling will compound their advantages while weaker operators get replaced.

The convergence of traditional finance and Bitcoin infrastructure is the largest theme of all. Robinhood acquired Bitstamp. PayPal launched a stablecoin. BlackRock launched a Bitcoin ETF. The most valuable companies of the next decade will not be "Bitcoin companies" as we have historically defined them. They will be financial infrastructure companies that treat Bitcoin as a native asset class alongside equities, fixed income, and FX. The firms that build the connective tissue, the plumbing that lets a pension fund allocate to Bitcoin with the same workflow it uses for Treasuries, will capture outsized value.

At Early Riders, we invest in digital infrastructure at the frontier. The fifty companies here are the story so far. The next chapter belongs to the builders who understand that Bitcoin's value is not only in holding it, but in building the systems that make it useful.
