What prevents real-life robberies in the hypothetical future where Bitcoin is widely used? What prevents the following real-life robberies from happening in the future where Bitcoin or similar cryptocurrency is widely used? Robber A goes to an infrequently-visited street vendor and buys a pack of gum with Bitcoin. Robber A now knows the address of the vendor. Robber A can sit and wait until someone (Victim A) purchases something from this address and has a very large Bitcoin balance. Robber A can follow and rob Victim A for their entire Bitcoin wallet. More generally, Robber B goes to random persons house with a gun and demands a Bitcoin transfer equal to Victim B's full wallet. Am I missing something because it seems incredible easy for people to do? Today cash, credit, and debit robberies have preventions/limitations in place to thwart very large robberies. I'm not seeing the same preventions for Bitcoin. http://ift.tt/2zQkVNA
