New projects these days considered as shitcoins already since they aren't giving that much profit especially in the long run. And finding a good project required a lot of knowledge about how the coins being made by someone and what is the purpose of making it. All of these thousands of altcoins existed I'm sure some of them are just a copy of the old or existing one.

Consider a new altcoins as a shitcoins or a pump and dump coins which is literally explains why they called as shitcoin.

If he's ready to take the risk, we can do nothing but advise him not to participate too much in the new project. If his strategy is hit and run on a new project, he can stick with it, but he should be careful because any project can become a scam. We can refer to a project that has developed first rather than choosing a new project that doesn't know how it is progressing so that we can avoid the project being a scam.
