Exchanges used to offer more than 10% APR rate for USDT staking but now they have reduced it a lot. I used to do USDT staking on Binance because back then they offered higher interest rates than banks. But now I don't. However, you can stake FDUSD on Binance regardless of how low the annual interest rate is. You will get free tokens in the form of airdrops from every Launchpool on Binance. From which you can earn a good amount. If you have $5000 FDUSD holding then you can get at least $20-100 from each Launchpool. If you calculate that, your annual interest rate will be much higher
Yeah it's more profitable than staking, but I heard that as the time goes, the reward is getting smaller and smaller, especially the recent launchpool which is Hamster Kombat. Unfortunately there are no profitable ways except you want to gamble by purchasing low market cap coins which offer huge amount APR rate.
Too many people are joining launchpool which make the reward getting smaller and smaller.
