some of the altcoins at stake are not all good. look back at the liquidity of those altcoins. Staking can give you an advantage, because staking is a very good way for us to use crypto. if you are risking it is the same as trading, you should be able to re-analyze the state of the market.
Those coins that have low liquidity, they're the ones that have the higher and unbelievable APY. But that doesn't really make sense because there's a low volume on it and it's not ideal.
While for those coins that has a good volume and liquidity, they're the ones that usually have the lowest APY and that's normal just like the banks because they're profitable and a lot are into it.
