Depends on the meme. Most memes pump hard and then dumps hard. But there those specials ones that the community of an L1 tend to gather around with. As I already said, in Ethereum it's memes like SHIB and PEPE. In Solana, there's BONK, WIF and FARTCOIN. In this new and hottest L1 called Hyperliquid's HyperEVM, there's BUDDY.
But don't take my word for it as I don't really know. Let's just talk again around October or November to see where it's at. That's 6 months... Enough to see if BUDDY has legs.

Even those ones, do not do so great for the long term. Shiba for example, look at it, has it been great, has it climbed up ranks? Nope, so it's clear that for the long term we are not seeing them do any great. Not Bonk, not Pepe, not Buddy. They all peaked at some point and did stay up longer than others, but they still fail to climb up the ranks, so it is not going to be ok at all. We need to realize, no memecoin does good for years.
Some pump and dump within a week when they are terrible, and some stay for a year maybe at most but then fail to go up, but all of them suck. We should not be putting that much money into this, it should not be good, we should try to avoid it as much as we possibly could. That would make a lot more sense, and could bring us more profit if we just invest into proper high rank decent coins.
