I think they'll be around for some time, since there are people who find some use for them, I guess. Delistings will probably reinforce decentralized p2p exchanges.

Personally, I don't case about any of them. I like PoW transparency at the base layer and having privacy options on top of it, like coinjoins or MWEB on Litecoin; or built in other layers, like confidential transactions on Liquid.
