The VP of a certain insectonymous mining manufacturer recently bought a fancy car and a house worth half a million $, and paid with bitcoins (through Bitpay or some such).  More precisely, he paid with bitcoins that he "test mined" over many months with equipment that he built or bought with preorder money from thousands of clients who only got their equipment when it has become uneconomical.

So, he did not put any money of his own in the deal.  Guess who actually paid for his 0.5 M$ house?
