What is the criteria for feature altcoins?

[lksufrr]

From my point of view your question is quite incorrect. But if I have understood it in the right way, features depend on altcoin's base of creation.

I think it is connected with cryptocurrency's base and common way of working. The foundation is the determinative characteristic here and you should rely on it.

A platform is must with a use case for long term of the coin. Without that I dont think any coin will survive, they will be just pump and dump coins with no meaning.

I would say you rather do some good factual researches that will make you get a good result in the best criteria of Altcoin.
