Yes, every wise and serious investors do always do that. If you do that then you will find yourself investing on the proper coins only and not those who are considered to be a junk. I don't know why there are people who chose to invest on a junk coin. Did they really believe on that old saying that there can be treasures on them?

In real life, maybe but not in the world of cryptos as everything here works differently. Only those greedy coin developers are going to be happy if you keep feeding them. I think that all wants to be successful but unfortunately not all are doing it the proper way, that is why there are still some who are unsuccessful.
