I have seen many projects that are very good, and that always want to enter the best exchanges,
Agreed, there are many good projects that are not listed on any tier 1 exchanges.
but I do not know what happens to them along the way, something goes wrong and they do not enter, that sometimes makes those projects collapse.
Disagree with this your point that it collapses or dies just because it is not listed on the Tier1 exchange then I don't think it's a good project or the project team does not have the ability to grow their community.
Because we all know that tier 1 exchanges only lists good projects but they must have large community support.
