I believe in bitcoin but sadly not humanity. If people actually weren't so ignorant we would have already stopped using fiat money long ago but nobody really cares to educate themselves about the corrupt system of economics. Same with politics really. Doubt anything will ever change any time soon.
What you think is not so easy to change the whole system of currency of the world to change in Bitcoin withing overnight everything takes time before it is implemented, still their are so many bugs in Bitcoin blockchain problem, once the Bitcoin Block chain problems are sorted out and it is running on mainstream then their are so many others who are ready to opt for Bitcoin technology.
