Not every project uses the same calculations and rewards of crypto staking. Some coins provide higher rewards than others, so the yearly rewards of crypto staking can differ. Also remember that these rewards can change over time.
You can maximize your rewards from staking. For example, by choosing a Staking pool with low commission fees and with a promising track record of validating many blocks. The latter also minimizes the risk of the pool being penalized or suspended from the validation process.
