Nobody likes gold because you have to use a middle man and have to keep that shit in a bank. Bitcoin just needs to get a domino effect going to gain more popularity. Im thinking the etf would just be one of the dominoes. Everyone knows what gold is where hardly anyone on earth has any idea what bitcoin is. If the government isn't trying to regulate bitcoin it means they do not see it as a threat yet. When they start panicking and try to regulate it it means we are winning the battle. With decentralized exchanges regulation is meaningless anyway. Getting setup with bitcoin is 100x easier than figuring out how to buy gold.
