I think it's not really without risks because you first have to buy the TFS tokens before you can stake them... That means you buy them for a certain price, you'll get extra tokens and in the end you'll have more TFS tokens. So far so good. BUT if the TFS rate drops, it's very good possible that the value of your total TFS is lower than the value of your initial TFS when purchasing (You'd get less USDT e.g. than what you've been spending initially) !BBH
