I bought SUPER and DOGE, both have already made me lose more than 60% and I don't care, I either let it go to zero or I refuse to sell and end up with crumbs

$DOGE My God, I've already lost more than 50%... 3 thousand USDT... It just keeps falling... Will it fall even more? What to do? Sell and buy if it falls more or hold? Is anyone else in this situation?
