Major players have entered the Blockchain industry.  It is delutional to think that  gold will be bit coins. Rather as the blockchain element, is doable on an exchange basis trade for trade, trade by trade only with standards to fully validate the process of a gold transfer from buyer to seller, this where the GOLD asset  validation will rack up the real worth in a free and open exchange GOLD market for personal ownership of/for GOLD.  As GOLD is real money and bit coin is fictional  ownership of a non-possesional theoletical asset, GOLD exchanged via blockchain is where what you buy is what you get to own, in a real GOLD transation via a  blockchain exchange market broker.  You will be the seller or the buyer.  If you are a shrewd trader you will do very well here.  All IMO!
