"Unbank Yourself" was Celsius Network's slogan. The irony is that millions of people took it literally: they moved their money there believing it was a bank, just a more generous and honest one. 17% APY on stablecoins, an app that looked like any bank's, a button called "Earn," the feeling of a deposit account. Years later it turned out this was never a bank, not for one second — not in regulation, not in insurance, not in what actually happened to the money inside. The word "bank" only ever lived in the marketing copy.
Celsius and BlockFi collapsed in the same brutal year for crypto, 2022, on different paths that converge at the same point: both companies sold trust that was backed by nothing legally binding, and when the market lurched, there was no floor underneath it.
The word "bank" without a bank
A real bank is not just a place you deposit money for interest. It is a charter, a regulator that checks capital ratios, reserve requirements forcing part of every deposit to stay liquid, and — in the US — FDIC insurance covering deposits up to $250,000 that pays out even if the bank fails on a Monday morning. None of this exists for the love of paperwork. It's a set of guardrails specifically designed to stop a bank from betting your money on something too risky.
Celsius and BlockFi had none of that list. Formally, both were fintech companies offering a product best described as "interest paid on deposited crypto" — not a bank deposit, but something between a loan you made to the company and an investment product. Regulators spent years arguing over the legal category, while the companies kept calling it "Earn," "Interest Account," "yield" — words that live in most people's heads right next to "savings account." The difference surfaced exactly when it was too late to matter.
Where the money actually went
No company pays 8-17% annual interest for years running out of generosity. That yield comes from somewhere — either real profitable activity or the money of the next depositor in line. Celsius and BlockFi took customers' deposited crypto and put it to work: lending to institutional traders and hedge funds, staking, parking funds in risky DeFi protocols, trading on their own account. It's the classic banking model — take short-term deposits and put them into longer, riskier assets — minus the capital requirements, minus the supervision, and with almost no transparency about what actually happened at the other end of the chain.
One of the biggest borrowers in this market was Three Arrows Capital (3AC), a large fund that had, among other bets, gone deep on the Terra/Luna ecosystem. In May 2022, Terra/Luna collapsed to near zero within days, wiping out roughly $40 billion in market value. 3AC, holding a substantial position there, went down with it and defaulted on its obligations in June 2022 — including outstanding loans to BlockFi. BlockFi had to absorb that hole with its own capital, booking a loss estimated at tens of millions of dollars.
The domino chain: June-November 2022
What followed was the classic chain reaction crypto has already seen more than once: panic after Luna and 3AC drove depositors to demand withdrawals from anything structured the same way. On June 12, 2022, Celsius froze all withdrawals, citing "extreme market conditions" — language that stood in for a simpler truth: the money could not be returned to everyone at once, because a large share of it was tied up in illiquid or troubled positions. On July 13, 2022, the company filed for Chapter 11 bankruptcy.
BlockFi held on longer, partly thanks to a $400 million credit line that FTX extended in July 2022, paired with an option to acquire the company. Sam Bankman-Fried spent that summer publicly cast as the rescuer of crypto lenders battered by 3AC's fallout. The rescue turned out to be a delayed-fuse bomb: part of BlockFi's own funds sat on FTX's platform, and the credit line itself came from an entity that collapsed even faster than Celsius had, in November 2022 — that story is covered in detail in our separate piece on the FTX collapse. When FTX went down, BlockFi lost both its lifeline and the hole it was supposed to plug. On November 28, 2022, BlockFi filed for bankruptcy too.
The fine print that decided everything
The quietest and cruelest detail in this story isn't in the loss figures — it's in a user agreement almost nobody read. Celsius's Earn program Terms of Use stated that by depositing crypto, a user transferred ownership of it to the company in exchange for a promise to return the equivalent plus interest. Legally, this was not custody — it was a loan from the user to the company. In January 2023, the New York bankruptcy court (Judge Martin Glenn) confirmed exactly that reading: assets held in Earn accounts were Celsius's property, which meant Earn depositors were not owners of their own coins but ordinary unsecured creditors, standing in line for repayment behind anyone holding a secured or otherwise priority claim.
That's the exact thing that can never happen to an insured bank deposit — the law already decided, in advance, who you are: a depositor with a government-backed guarantee. Here, the decision was buried in a clause of a user agreement accepted with a single click at sign-up.
Our record. This is a textbook case of the Shadow Isis — the archetype of control disguised as care. The interface said "we're safeguarding your savings," the button was labeled "Earn," the emails from the company read warm and familial. The actual structure of the deal was the opposite: not custody, but a transfer of ownership; not care for your Ka, but its temporary seizure in exchange for a promise. The Scales of Maat don't weigh the tone of a customer-support email — they weigh what is actually written in the document you signed.
The people behind the numbers
The gap in accountability between the two companies turned out to be a lesson of its own. In February 2022, before the crash, BlockFi had already been hit by a regulator: the SEC and regulators from roughly thirty states settled with the company for about $100 million over its interest accounts effectively being unregistered securities. After the bankruptcy, no criminal charges were filed against BlockFi's founders. Celsius went differently: in the summer of 2023, founder and former CEO Alex Mashinsky was charged by multiple agencies at once — the SEC, CFTC, FTC, and the Department of Justice — including fraud and manipulating the price of the company's own token, CEL. In late 2024, Mashinsky pleaded guilty to two federal counts, and in 2025 he was sentenced to real prison time — reportedly around 12 years.
What this means for you
The check is simple, and it's worth doing before you send money, not after withdrawals freeze. Don't ask "how much interest do they pay" — ask "what does the agreement actually say about who owns my assets while they sit with this company." Is this product insured by a government body, or is it a private company's promise. Does the platform disclose where deposited funds actually go, or is the yield explained away with vague phrases about "efficient asset management." If the answer to any of these is "trust us" with no document backing it up, you are not a bank depositor. You are an unsecured creditor of a business whose model you can't see and can't influence — and you usually find that out on the day the withdraw button stops working.
