Probably yes. The dexes are the strenght of decentralization on defi projects. Without them the altcoin markets will be doomed. As far as I can see, the problem here isnt them but the community has been wrecked by previous landslide dumps last bull run. Apparently the nft era has gone down and those liquid tokens associated with them got fallen too. Maybe a new era and something new would keep them alive again and probably keep them to continue. But all in all, these dexes are important to trigger another bull run aside from bitcoin sky rocket time waiting.
