ETH and Solana are also altcoins. You are lucky that you made a good decision at the last moment of bullrun which many could not. But I think it would be better if you could convert your assets to USDT. Because btc, eth and solona are also bleeding.
Isn't there a better way than that? because if he converts now, then he will incur a loss, but if he still keeps it until waiting for the price of btc, eth and solona to increase again in the market, then that is a very wise thing I think, because right now the price of the three coins is so low that it will shame if someone dumped it by converting assets to USDT.
