Any memecoin that comes out with the claims that they'll make all their investors rich is a scam that wants to steal their investors money and exit scam. There's nothing wrong hyping your project because of the confidence you have in the project and because memecoins need hype to do very well but as you hype don't promise your inventors an assurance of making profits.
You can hype the project of doing well but don't be specific of how much they'll make as investors will begin to see your memecoin as scams. Before anybody invest in a memecoin, they should already know that they'd taking a big risk as the memecoin can do well or become a scam. If you don't want to risk losing your money then investing in Bitcoin as it's the only safe option.
But if you invest in altcoins be ready for anything that happens and then when you invest in memecoins be prepared for the worst because that's where the highest pumps and dumps schemes happens. But that doesn't mean you can't make profits from investing in memecoin, you can make profits but you have to be smart about it and not marry any memecoin you invest into.
