All of these developers with experience in other projects have been beginners, I just think it's an exaggeration to think that only veterans can have a good idea and a good project execution.
I would never say that only veterans will be able to create a good cryptocurrency. But at the same time, let me ask you something. Will you be willing to invest in some altcoin, which is being developed by a few college students with no previous experience in this sector? I would avoid such projects, even if they have a good idea and project execution plan. The project may be good... but we need to think about the viability as well. With such a team, will they be able to get the necessary funding?
