And bitcoin has faster transactions than the bank and more secure I guess.
Neh, you're wrong. IMO, bitcoins aren't that secured as compared to bank. Bitcoins, if ever hacked, you loose 'em forever but it isn't the case with the banks.
Well, you pay insurance for those bank hacks. The banks simply pass on the expense to you. They have to because online banking is simply not that secure. Bitcoin is far, far more secure, far faster, and far cheaper. Indeed the fastest, cheapest, and most secure banking system in history. Which are among the reasons it is worth billions and will likely be worth trillions.
