I only believe in the top 10 altcoins - they are more reliable. The rest of the altcoins cause me doubts and I think that in the future they may well disappear, although it is possible that new coins may appear that will replenish the list of top ones.
I do not agree with you. Far beyond the top ten alternative coins, there are a whole host of projects in which life is in full swing.
According to my conservative estimates, similar projects can be found up to the 500th line of the top list.
Indeed, the most important thing in alternative projects is how the team works, and how the implementation of project ideas is progressing.
If these factors are present in the project, then it can be called promising, and in the future it can easily move from the top 500 to the top 100. After all, projects that stop in development quickly fall down the list.
