From the experience I've had at Biswap, the passive income I get is very good, I won't give you an idea or profit percentage, because a percentage like APY will not make the price of the coin you get make you profit, the price of the coin will definitely go down because a lot people who get coins from staking and they sell them.
Recently I sae the SAFUU platform give more than 300k% APY, but I believe the price of the coins produced will decrease as the number of coins sold after staking increases
