BlockFi Review

BlockFi Review: The Crypto Lending Pioneer

⚠️ Important Notice: BlockFi filed for bankruptcy in November 2022 following the FTX collapse. Withdrawal restrictions were applied. This review is kept for historical and educational reference.

Background

BlockFi was founded in 2017 by Zac Prince and Flori Marquez in New York. The company pioneered the concept of interest-bearing crypto accounts (Bitcoin Interest Accounts), allowing retail users to earn up to 9.5% APY on crypto holdings — rates that attracted billions in deposits during the 2020–2021 bull market.

What BlockFi Offered

• BlockFi Interest Account (BIA): Earn interest on BTC, ETH, and stablecoins
• BlockFi Loans: Borrow USD (or stablecoins) against crypto collateral
• BlockFi Credit Card: Visa card earning 1.5% back in Bitcoin rewards
• Trading: Spot trading between supported assets

The Collapse

BlockFi was heavily exposed to Three Arrows Capital (3AC), which defaulted in June 2022, and had a significant credit relationship with FTX/Alameda. When FTX collapsed in November 2022, BlockFi suspended withdrawals and filed for bankruptcy.

BlockFi creditors entered a lengthy bankruptcy process. The recovery for depositors was uncertain and significantly below 100% for many account types.

Lessons

BlockFi's collapse reinforced that:

• Lending platforms are not banks — deposited crypto is loaned to counterparties and is at risk
• High yield = high risk: 9.5% APY on Bitcoin was not risk-free
• Counterparty risk is real — even reputable platforms can fail when their lending counterparties default

Conclusion

BlockFi was an innovative product that demonstrated both the potential and the risks of crypto lending. The collapse, along with Celsius, Voyager, and Nexo's own near-miss, marked the end of the first generation of centralised crypto yield products.

If you are looking for yield on crypto, only consider regulated, transparent platforms, and never commit more than you can afford to lose.
