The fact that you said bitcoin will not last is simply ignorant.
There are far too many backers of btc that will not let it fail.
You need to use logic when conducting opinionated statements.
The future of bitcoin is hard to determine because it is increasing surprisingly or decreasing it value super fast. It is hard to tell because we are not a statistician. In my perspective bitcoin will continue to increase its value until 2018 and its value will fall in 2018 also. Bitcoin a has future to be a currency in some country and it might have an atm account. Bitcoin has a chance to be the world currency when it comes in the online network. Bitcoin will continue to change the world when it comes to currency.
