I invest in new projects, but very selectively. And a new project for me does not mean that it only appeared on the Internet yesterday. I prefer projects that are at the very beginning of their development but have already shown some results. The project needs to be highlighted by its team and be in touch with its community. Strictly follow the terms of your roadmap, and not be a "pig in a poke".
Your strategy is very good, but note that however when one follows all those conditions, they can still scam, this is what many did with NFT games, the roadmap was the best, even the identities of all the devs and the team in general and even so they stole, that is, many times those rules do not work, what if I saw that it works is that the coin or project manages to reach Binance or another Exchange so that it can be more serious, it is the only condition that I have seen that if it works when choosing a project, but when they are in decentralized exchanges, what you say does not work.
