The reward from crypto staking is a percentage return. It is similar to a dividend payment or the interest earned in a checking or savings account.
How much you can earn with crypto staking depends entirely on your deposit and the crypto currency you choose. Fluctuations in prices can also affect your returns. Therefore, always check in advance what your investment can yield in a given situation.
The return you earn on your crypto coins is paid out weekly on Monday. You can view the interest you earn per coin in the staking menu.
