That sounds too sweet to be true. Are you sure you can withdraw money? Have you already tried to do this? You know 99% of all investors who believe in such easy money finally find out that they just wasted their time. Look on other exchanges and their offers. Here you can find Binance locked staking: https://www.binance.com/en/pos. Now they have 110%/month AXS locked staking (have limit on the amount of coins investor can stake). That is the best proposition because the coin is very risky and can drop any moment. Other propositions are not so cool, but  good. However, this is not 5%/day on huge amount of coins. Giving such percents will bankrupt the exchange.
