Now, onto your actual question: Meme coins vs Presales. Look, I'm not gonna sugarcoat it for you. Both have their risks and both can be profitable if done right (or wrong, depending on how you look at it). But here's the thing - why are you even asking us? Can't you just use your AI to get some solid insights?
I will rather sit on the fence and watch the market do his thing on miss out meme coins or presale token than participate in any of them. Meme coin are now the most risky thing anyone will ever think, anybody can create something just for fun and you don't know what's on their mind and you expect me to put my hard earn money into such coins? I wouldn't try it and presale as well, the history of this two things are not good for crypto.
I don't know why you also think AI will give you really insight, there are many things that has happen in crypto that I think if do my own research, it will help me than depend on AI. It's even better to do research on good coins than go for the OP you mentioned, you are not getting scammed when you buy coins on the market you know and if the market is good, you will definitely make some gains.
