other than doge and shiba, I don't think there's any more memecoins worth holding on to in the long term. very rarely do we hear that there is a memecoin that has a push from a big company except for those two coins. if there's a meme coin worth holding on to in the long term, it's doge and shiba. if you want to focus on one meme coin, it's doge.
The two meme coins are still worth investing in because they already have a lot of support from the binance exchange, but another alternative I see an opportunity for a meme coin called Floki because it is integrated with Link and sponsors the Napoli football team and many other teams. Not investment advice but maybe worth considering.
