your advice is really good. when we realize that we cannot analyze and research a project properly. then it's better not to force yourself into the new project. unless we really know it's a good project with obvious utilities. because we see behind the project being supported by great people. then it is allowed in.
because lately there are many new projects that are not serious in making projects. although the whitepaper and roadmap are written long term. however, often in reality project work is far from the roadmap. or ends up dev running away. and be a fraud project.
to join a new project if we get to participate in the presale then it is better to use the "hit and run" technique. but still the risk is very high so said DYOR is always present in every new project.
Well even if it applies Hit and Run and Dyor but still we also have to research first, almost thousands of new projects come every day even though some of them have good projects but still it's like looking for a needle in a haystack there which will be very hard to find.
I personally prefer to be in something that is certain compared to looking for something that is not sure there
