Cool statistic, but meh. Comparing the marketcap of a digital asset to a business simply just doesn't make that much sense. Call me when bitcoin reaches gold's marketcap. 
Bitcoin reaching Gold marketcap will be the biggest thing to ever happen in the blockchain and crypto currency space lol and i believe that it is achievable. I also feel bitcoin above Visa will be a momentarily event which we should milk well as traders / investors. It is getting clearer each day that Bitcoin is the future.
