The question is why do some people generalize all Altcoins as bad? considering there are over 3000 of them out there. One would not have the time to go through each project one by one. to analyze the project. team etc everything behind each crypto project.

Only one reason that crossed my mind: Because people who think that have ever suffered a loss or bad experience with altcoin chosen. In fact, there are a lot of potential altcoins that are very profitable, assuming the top ten coinmarketcaps deserve that title. So it is not fair if it is generalized and equated with new coins or tokens which have not been proven to be of quality that are even made with just playing without a clear purpose.
