Answer2:Yes, in general, staking of USDT can yield returns between 2% to 4%, depending on the specific blockchain network and the project being staked. This is due to the fact that different blockchain networks and projects offer different levels of rewards for staking. For example, some projects may offer higher rewards for staking USDT, while others may provide lower rewards. Additionally, the amount of rewards also depends on the amount of USDT being staked, as larger amounts often yield higher returns. Ultimately, it is important to do your research and compare the different options available to ensure you are maximizing your return on investment.
