BlockFi interest rates are tiered and vary between 0.10% APY to 9.50% APY. The specific interest rate depends on both the amount and type of crypto held. As an example, if you hold less than 40,000 USDT, you can earn 9.50% APY on your balance. However if you hold more than 40,000 USDT, then you’ll earn 8.50% APY. Refer to the table above for complete details.
