i havent had good results on ethermine for years
too many ppl there with 100x+ ur hashrate
i switched to hiveon for this reason cuz they payout stale shares
ive tried a few others like sparkpool which payout as well as hiveon but u have to pay ur transaction fee

i guess after u get ur payout u gotta just find a better pool
i also section part of my hashrate to other coins
mainly cuz i still have 4GB cards that cant be on eth
so ive been mining ergo and etc as well as eth
