If you can't afford the thousands of ASIC miners and are considering staking, it's best to avoid staking platforms or coins that offer that percentage. They will soon drop. Since you mined ETH before it turned into POS, and if you still have your GPUs, check out the coins that you can mine with them through https://whattomine.com/
However, I think that the profitability of those other altcoins has dropped too. As for people like me who have the same plans before, I've concluded that buying Bitcoin and holding it will give me more returns and then less effort and less electric bills and it has no other way but to go up. So, the potential loss will be there in paper but it will be recovered once it's high again.
