Since you already have some altcoins, why are you trying to find them? How did you get these coins? Did you buy it or did you get a bounty? You can sell them instead of letting them die in your wallet
letting the altcoin assets that we have in the wallet doesn't necessarily make them die. sometimes there are some altcoins that we hold on our wallets for so long that we even forget that if we have these coins it can be beneficial too.
as we all know, the altcoin project usually takes a long time to develop the project until it finally runs. and it took quite a long time, initially it was like useless but after a while we held back the assets, it turned out to have very high value.
we must learn from the journey of bitcoin, because bitcoin cannot simply be as expensive as it is now.
