On my wallet about 80% of all tokens are not on any normal exchange. There's just a lot of garbage lying around that you can't even get rid of. Maybe one day, they will be sold. But it's hard to believe. I rather the keys to those wallets will lose.
just like me, there are many gift tokens that I receive but don't have a market yet, and even though there are some who already have a market but have very low prices so I keep saving it and hope that someday the price will go up and sell.
maybe if the market recovers there will be coins that can be sold.
