Most of the meme coins doesn't have any potential or any use-case at all.
Most of them are being created for the sake of profit. Nothing more.

Some of the meme coins are being labeled as "the coin of the community" that's why they're being created under a specific blockchain, but in reality, most of them don't have any benefit to the users at all except for profit (if they can get out with profit of course). Advantages? I can't think of any aside for the fact that they can give huge profits to a very few investors. On the other hand, that advantage can be a disadvantage of course because not all investors will make profit on meme coins because most will lose their money especially those who got FOMOed.

Overall, some of the meme coins might be a good short to mid coin to hold, but most of them are just trash shitty coins that are being created for the sake of profit.
