You mean these one:
https://coinmarketcap.com/id/currencies/x-cash/ ?
I also collect these coins from their airdrop stored in my paper wallet. Seem like these coin is dead last update tweet on 2022 and they never update again right now. Failed project I guess, to bad.
I think this X-cash ran a bounty here on this forum in 2018/19, or so. I can't be too sure any more if we're looking at the same project or not. Anyway, many of those projects back then went under and couldn't make any good showing. There are a good number of them I'm baghodling and wouldn't want to trash them yet. No one knows what direction this industry can take and the devs of those projects decides to list them, possibly to offload their bags too. Early this month, I saw someone trying to provide liquidity for another supposedly defunct project – ONZ on Pancakeswap. If that liquidity becomes high to the point that the token will become tradable, hodlers will certainly have an opportunity to sell off their bags. I'm baghodling this token too.
