I think this is a difficult question, isn't it too big a risk to invest in projects that are just being developed?
You are right. The risk is too high when you invest in a project that is new and just being developed. If the project get abandon or fails (like most of the new projects..), then you will lose everything you have invested. Even if the project doesn't fail, it doesn't mean that you will get a good return on your investment. There are several projects that were well developed, but there wasn't anything special that would have made the price skyrocket.
On the other hand, if the project has a good roadmap and a promising team, then you can invest and get good profit in the future. By the way, it seems to me that the CheckDot project, which is associated with the verification of other crypto projects, may be quite promising in terms of investments.
A good roadmap doesn't indicate anything. And projects that tries to shill for them are likely scam. I have been seeing a lot of checkdot shillers over here.
