The truth is people want to make a profit in the dex exchanges and they still buying any tokens in that site which have a good vision in the long term. But you can do analyze before you decide to buy any token because no matter what, that is a good way for you before you buy the tokens. By analyzing, you will find good potential coins at the dex. I think the volume is not too big depends on the centralized exchanges, but sometimes, the tokens are getting a list on the major exchanges, so we have a double chance to make a profit.
i see that profit is the one that your looking on a dex but for me . its not about the profit that ive been looking for but i prioritize the the service if the dex is user friendly or not and if it listed my coins .
luckily there are some dex that already list my coins , the coins that i recieve from a bounty and airdrops . i dont buy coins on a dex but i only sell my coins on them .
what i also love is that dex are private not unlike to cex that reveals our personal infos .
