Tidex is a cryptocurrency exchange where you can trade different coins. They recently announced that they will be offering staking service for those willing to stake USDT. They are offering an annual return of 12% on USDT which is very high given the fact that USDT is a stable coin and stable coins are known to show very little volatility. I don't know a bank that offers more than 6% annually on your money and this is why 12% sounds great.

What Is Staking
Staking is the process of holding funds in a cryptocurrency wallet to support the operations of a blockchain network. Users get rewards every day for simply depositing and holding coins and tokens on Tidex as they normally would.
Staking is very similar to a fixed deposit. You just need to put your money in a crypto wallet and lock it for some time. Unlike banks, here you will get daily returns which means that even if you unstake your money before maturity, you will still have earned returns. In the case of Tidex, unstaking takes 24 hours which is pretty reasonable. The minimum amount to a stake is 100USDT.
