Many here keep denying that it's difficult to use. That's a fact but what it's worse is that there's actually no problem to solve. Bitcoin doesn't do anything better than Paypal or CCs. Common people don't need Bitcoin in their lives unless they want to invest long term. People here mentioning Paypal is refundable as if was a disadvantage? you think that's a con for common folks?  Do you think my mother wants to use Bitcoin (which is non-refundable) so the minute she makes a mistake she will lose all her money? Really? Because she will make that mistake sooner or later I guarantee you, there are decimals, authorization keys, brain wallets, address as long as long as line of code, qr codes, and you think being non-refundable is a plus? I think Bitcoin is a unique technology don't get me wrong but is in its infancy just as the internet was in the early 90s, it's still just for curious and tech savvy people. In this case it also attracts investors and traders.
