I don't understand how people could say bitcoin is instant. It makes me think they've never actually tried buying anything with bitcoin. All the bitcoin stores/processors I have used require 3 or more "confirmations" with each confirmation taking an average of 8 minutes which means each purchase takes at least 24 minutes and sometimes even several hours. When I tried to sell things with bitcoin, customers told me it was a hassle when a Paypal or credit card transaction completes in seconds. This is the main unfixable problem with bitcoin and that is why I believe it will not take off.
