if waiting for Altcoins like Aurora and BTT it looks like you bought them to decorate your wallet so that it is not empty, while ETH and BNB can be used as gas or fees, your idea needs to be applied to those whose wallets are empty
Aurora and BTT I usually use for short-term trading only, because they are not very suitable to be made in long-term trading, and these two coins are not really to decorate the wallet, but for temporary options when market conditions are good
