Looks like it turned out right for Meme coins, market is very bearish right now for Meme coins.
Considering only to buy a useful projects has better chances and potential.

That is the real worry when you buy meme-coins. You don't know if the bear run has started or the meme hype is over and it's time to sell the coins. If you invest in a legit project at least you know the project is yet to launch and even if the bear run is causing the crash, it should be recovered well once the project launches.
Some people do well but it’s a minority really & you really do risk losing everything with these type of investments. Stick to bitcoin & other established alts rather than risking with meme coins.
Some people will always do well even during the bear runs and yes most of the time the creator/owner of these meme-coins are the ones with the highest profit and from whose pocket it goes? Those who buy these meme-coins without actually knowing when to sell.
There is no problem trading these meme coins but only the sharpest traders will benefit and if you are holding meme coins, you better stop trading.
