visa charges you 3% for every transaction. bticoin is less than 1%. Bitcoin transactions are much faster than 4 hours, but no one ever said they were instant, so idk what the hell you're talking about. Bitcoin will never be printed to more that 21 million coins, while trillions of USD are printed every year. Bitcoin will be the currency of the future, but don't worry, even people completely illiterate in technology will be able to benefit from the technology because people smarter than you and me will build apps which will make money transfers a matter of a few clicks, with blockchain as the underlying thech.
