These days lots of places are supporting staking and you may gain up to 10% per annum but the question is, will you able to get good ROI in USD or BTC/ETH rates? Definitely NO. For example, I tried staking Tron when its price were trading around 500 satoshi and they announced free air-drop of BTT tokens on monthly basis for holding TRX in some specific exchanges but see where TRX is trading right now; I agree I got good amount of BTT tokens for free and up to 6% returns for my TRX balances but its worth is not good in terms of BTC/ETH values.
