Interesting is that they rate Bitcoin as more valuable than Gold, they compare Bitcoin as rare as Diamond.
I'm not sure if liking Bitcoin to diamonds is a good thing or not. Diamonds were for a long time controlled by cartels and while their mining might be a bit more decentralized these days, the diamond cartel still has strong influence over the industry. I've heard people say that diamonds would be nearly worthless if the market was flooded with them and while I don't know how true that is, the idea that diamonds are plentiful but held in the hands of few to make them more valuable when sold should be troubling to anyone trying to bring adoption to Bitcoin. I've been saying it for a while that Bitcoin has been hijacked by Wall Street and it's valuation pumped in order to bring them more management fees. That is starting to sound a lot like the diamond market...
