This is a very wrong assumption, I mean how can someone in his or her right senses even assume such a thing? If they say making money in crypto currency is like making money out of thin air, then what do they have to say about making money with Forex trading? That's also making money out of thin air, before I made money in crypto, I had to either invest my fiat currency in crypto, it rose and I made some profit or do some crypto work like joining in bounty campaigns to promote projects and I got paid, how is that making money out of thin air.?
