If you think Binance Smart Chain fees are high then crypto market may not be for you. It's literally the cheapest major chain right now. You can do every transaction for 15-20 cent, 50 cent at most.
There are plenty of staking options though yields vary from %3 to %300. Don't forget that when you stake a coin you have to be careful about their price too. For example a coin may give you %100 return in a year but if it loses its value more than %50 in same year then you will be in loss total. I tried a lot of yield farming on BSC and liked most of them but right now I don't have a favorite due to irregular market moves and uncertainty in the market in general.
