It's common to see the use of coin names that are almost the same as memecoins which are already popular. and such a strategy is no surprise to us.
However, there are also memes that succeed and there are more that fail. We can't say that the project OP intended will be good enough in the future. but it's better to be careful. If you really have to connect a wallet, you're right, it's better to use a new wallet and not use the main wallet. just to be careful because there are quite a lot of people who have lost assets because they were careless in connecting their wallet.
Honestly, when you compare the number of memecoins that got to a decent place versus all the ones that are not anywhere, it means that we are not going to really see most of them succeed, and so why would we really end up with anything better? I would invest into something old instead of something new, this isn't about meme by the way, I think it's quite clear that we are going to end up with a good return here and there if we stick with the old ones.
Meme projects are not something I enjoy investing into, some people may like them, I just do not see the benefit in them to be fair and that's why I try to stay away from them as much as I possibly could. This is why I believe that the best we can do would be investing carefully with big names like bitcoin and ethereum.
