1. Your general opinion of this. How good of an idea is to invest on new binance launchpad projects at this time?
It depends on what kind of investor you are. If you are willing to take high risks by investing this early on then by all means, go do it. I don’t think we can specifically tell you whether your decision will be good or bad.
2. How can I detect the best of them? I know about the usual due diligence stuff like the team, the community, tokenomics, etc. But is there anything else? Like some rating system or a site that reviews them or something? I've found these kind of information about launchpad projects to be a bit rare.
Nope. As far as I know there are little to none websites that offer ratings for launchpads.
When choosing which project to invest in, try to consider yourself as well and your goals and objectives and check whether it aligns with the project’s.
