Casinos have existed for decades, and yet people still keep going there and losing all of their money there. What gives? You can downright reject anything crypto currency related because it fails basic economic theory. There has never been a financial instrument that gives risk free 10-30% yields. No economy has ever grown at that rate. If it is a company what real products or real services does it provide? Where's the value add? Exactly, there isnt, it's a plain old pyramid scheme hiding behind mumbo jumbo jargon that only impresses the mentally challenged.
