Celsius, BlockFi and Genesis All Promised a Fixed Yield on Your Crypto, and All Three Collapsed. Here's Why DeFi's Own Lending Isn't the Same Bet

Imagine you deposited some crypto in 2022 and were promised a fixed yield, paid like interest. Then one morning the app says withdrawals are paused. That happened to hundreds of thousands of people. The Celsius, BlockFi and Genesis collapse took three of the biggest crypto lenders down within about six months.
The three firms did not fail for the same reason on the same day. But they failed in the same way: you handed over your coins, they lent them on, and you had no way to see what happened next. This post shows how each one broke, and why DeFi lending (lending done by open software on a blockchain) is a different kind of bet, not a safe one.
A centralized lender is a normal company. You deposit crypto with it. It promises you a rate, say 8% a year. Then it lends your coins to someone else at a higher rate and keeps the difference.
That is the same business model as a bank. But there is one big gap. A bank in Indonesia is watched by regulators and its deposits are insured up to a set limit. In 2022 these crypto lenders had no such cushion, and you could not look inside the company to check the loans.
The key word is counterparty risk. It means the risk that the other side of a deal cannot pay you back. Here, the other side was the lender itself, and whoever the lender had lent your coins to.
Celsius paused all withdrawals, swaps and transfers on 12 June 2022, citing "extreme market conditions." At its peak it had held more than $20 billion in assets and had offered rates as high as 18% (Fortune). It filed for Chapter 11 bankruptcy, a court process that freezes creditors while a company tries to restructure, on 13 July 2022.
Later, a court-appointed examiner (an independent investigator) reviewed the books. Her findings, as reported by Benzinga and Forkast, were blunt:
The examiner, Shoba Pillay, wrote: "The business model Celsius advertised and sold to its customers was not the business that Celsius actually operated."
BlockFi took a different road. It filed for Chapter 11 on 28 November 2022, weeks after FTX, a large crypto exchange, went bankrupt on 11 November (Axios).
BlockFi had lent to FTX's sister trading firm, Alameda Research. In court, BlockFi said FTX and Alameda owed it more than $1 billion: $671 million on a defaulted loan to Alameda and $355 million frozen on the FTX exchange (Decrypt). Later filings put the loans to Alameda at $831.3 million (Benzinga).
BlockFi also had a regulatory problem earlier that year. It agreed to a $100 million settlement, $50 million to the US SEC and $50 million to 32 states, over its yield-paying Interest Account, which it had not registered as a security (Axios).
The lesson: a lender's safety is only as good as its biggest borrower. One borrower failed, and the lender followed.
Genesis was less known to everyday users, but it sat underneath other products. On 16 November 2022 it suspended redemptions and new loans, citing "unprecedented market turmoil" after FTX (Cointelegraph).
Genesis had already been hurt by the collapse of the hedge fund Three Arrows Capital in June 2022. It filed a $1.2 billion claim against that fund in its bankruptcy case (same Cointelegraph report).
The pause hit users of Gemini Earn, a product where Gemini's customers lent through Genesis. Earn had drawn about $900 million from 340,000 users (Fortune). Genesis filed for Chapter 11 in January 2023, owing its 50 largest creditors about $3.4 billion, with Gemini owed about $766 million (Bloomberg Law).
Many Earn users did not know Genesis existed. They trusted one brand and were exposed to another.
| Celsius | BlockFi | Genesis | |
|---|---|---|---|
| Freeze or filing | Paused 12 Jun 2022, Chapter 11 on 13 Jul 2022 | Chapter 11 on 28 Nov 2022 | Paused 16 Nov 2022, Chapter 11 in Jan 2023 |
| What promised yield | Rates up to 18% | Interest Account | Loans, and Gemini Earn |
| Main trigger | Balance sheet deficit of about $1.19B | Lending to Alameda and FTX exposure | Three Arrows claim, then FTX fallout |
| What users could see | Almost nothing | Almost nothing | Almost nothing |
The last row is the point. In all three, the customer could not check where the coins were, who had borrowed them, or what was pledged against the loan.
In DeFi lending, the lender is a smart contract, a program on a blockchain that holds the pool and follows fixed rules. Loans and collateral are recorded on-chain, so anyone can inspect the pool's balances and each loan's collateral ratio at any time. There is no private balance sheet to hide a hole in.
That removes one risk, the opaque middleman. It does not remove risk. Our earlier post on DeFi lending yield risk covers what can still go wrong: forged collateral, bugs, and liquidation cascades. Celsius itself even pulled positions off a DeFi protocol in June 2022 while trying to survive.
So the honest comparison is this. Centralized lending hides its risk inside a company. DeFi lending puts its risk in public code. You still take risk either way, but only one of them lets you look before you lend. If you are weighing stablecoin yield specifically, stablecoin yield risk covers that side.
A promised rate tells you what a lender will pay you. It tells you nothing about how likely it is to keep paying. Look at how the underlying coin actually behaves first. NetWort's Explore screener lets you filter crypto by volatility and maximum drawdown, the biggest fall from a peak, so you can compare assets like Bitcoin side by side before deciding whether any yield is worth the swings.
