Staking allows to have passive income but it will allow to have the passive income only if project is useful and the price of the tokens will continue to grow in the future.
most of the time the earning from staking overshadowed by the inflation if it's a shit project. instead if it's staking coins like USDT it kinda requires big capital that it's only suited for the rich people.
regardless though the key of staking is having big capital and investing in rather famous coins like BNB that way you gonna have bigger chance of creating reward that didn't overshadowed by the volatility and also could earn quite of reward at the end of the day,
if it's low capital that being staked it kinda wastes a time.
