You're right not all new projects are bad for investment, there are some new projects that have clear uses that are worth buying. But the problem is
it is not easy to find good new projects, based on my experience in the crypto world, there are more scam projects circulating. So our seniors in
the crypto world will advise us to avoid investing in new projects, because it is not easy to find good new projects. It is very important to have
good research and analysis skills to be able to choose new projects that are really worth investing in. Therefore if we feel that our analytical skills
are bad and we don't have much knowledge about the crypto world, it's good for now to invest in popular old projects first.
You can not conclude that all new project are bad projects when you know that alot of good project were introduce to be new before becoming noticable as a good project, the point is not really good or bad, but we have to know that some of the new project might be good in future time, and before you invest in any coin you to investigate very good so that you will know the project that is bad
