The primary benefit of staking is that you earn more crypto, and interest rates can be very generous. In some cases, you can earn more than 10% or 20% per year. It's potentially a very profitable way to invest your money. And, the only thing you need is crypto that uses the proof-of-stake model.

Not exactly - you don't get an actual real dollar a day. However, there is a daily reload bonus where you get some free Gold Coins and 1 Stake Cash.
