don't sell if you don't want to lose. the market is in the recovery phase, you have to hold the coin that you hold now. while if there is a lot of money, it is better to buy another altcoin before the crypto price in the market rises.
I agree with you, if you sell you will lose a lot so you have to hold it first. now the green market hopefully this can be a good sign for Crypto so you have to invest your coins because the market will move better. if you want to buy at the right time because of the potential for coins at this time the price is low and you can buy a lot with not much capital.
