For a long term holder/investor there is a serious risk to stake coins and tokens, and then not be able to take them back. Let say in https://atomicwallet.io/, STAKING PER YEAR - Cosmos ATOM 10%, Zilliqa ZIL 13%,ICON ICX 10%, Band Protocol BAND 13%, and Atomic Wallet Token AWC 20%. Is this reliable ? Who knows.
By the way, if you are interested I know one project with altcoins, where staking currently is ~1.2% per day, but there are some limitation for exchange, pm me, if interested, can send the link.
