Only a few projects and it's not all. I can say only a small percentages of the total meme coins in the market that have the intention to develop a real product like shiba with its swap service.
Shiba was increasing a lot again but it seems like that if this could be a very hard thing to did to reach 1 cent. Almost all of the meme coins were only offering gimmicks to the buyers and investors. Meme coins didn't have real value. Shiba may be a different thing that's not comparable with the common meme coin coz it's supported by so many whales. Even some big boys were also supporting this meme token like what they have done with doge coin. 1 cents may be easy but the time will tell. Shiba was growing so crazy right now.
Shiba is not "real project" just because it has a swap, I can create a swap for you in 10 minutes, literally 10 minutes, design would be required of course and I am not a designer so it would look bad, but all the features will be there and ready. Shiba spent probably a week or two on it at most and created a swap but that's about it, nothing about that swap shows any promise, it is a totally useless swap.
The only reason why people are showing interest to it is the same as why they are showing interest to shiba, it is a community hive mind and there is a hype around it and people are sticking to their guns. I am 100% certain that eventually it will not be able to get anything out of it and you will be upset that you didn't get out early enough.
