I agree with the comments in the article about the stuff this guy said. Bitcoin does not have intrinsic value, which is perfectly normal. It is indeed worth as much as people are willing to pay for it, which is the cornerstone of the free market. The problem is that this guy is looking at Bitcoin as a kind of valuable property, and then he's right that it's not like that. But Bitcoin, unlike stock/property/security is also money, and money is supposed to be like that. On the other hand, Bitcoin can be a profitable investment, but there's no wonder Mark Cuban does not see it. He's super-rich already, he has no motivation to risk or even learn something new.
