it cannot be denied that most projects are good and have quality products but ultimately end badly, especially for developers who register their projects in bad exchange. Well, there might be a number of reasons developers do that, but if so, surely a good project will not produce sweet fruit.
Of course it can be denied, most projects are either scams or just weak attempts to create something good, and the statistics are on my side when it comes to prove this, most projects fail because they are bad, it is not complicated, at the end it does not matter the exchange they selected those coins are going to disappear anyway no matter what they do, a good coin will survive being listed in a bad exchange and it will eventually be listed in a good one if their developers keep working on it.
