Bitcoin is used by terrorists to fund their murder and kidnappings, child molesters their child pornography, drug heads their poison. The only practical use for bitcoin is highly illegal and immoral activity that no mainstream bank would want anything to do with for legal liabilities. But bitcoiners don't understand cost benefit analysis which is why many of them end up in jail or broke with a condo full of fried GPU's. Anything practical or productive done with bitcoin can be done with currencies (actual money) at 1/1000th of the transaction cost (or zero) and 1000X the security and fraud protection. Bitcoin, the currency for suckers and criminals, which one are you? Cheers!
