why do you think that they waste time in vain? if this coin is traded on the market, then investors have invested their funds in it, and the developers have accordingly made a profit. There are many projects where the idea and essence are the same, because to come up with something new has been tiring and too costly. That's why so many coins and projects are fraudulent and do not bring results
tney re not wasting time not at all even if they fail because when you are dping something completely new you develop your intellect
