I think bitcoin didn't as it was expected to. What do you think about bitcoin in 2016?
why do you think bitcoin has failed? bitcoin is already a success and it will be forever. in 2016 block rewards will halve down to 12.5 ,price will increase?
Price should ideally double if the mining is to remain profitable at the same level as now. But you never know what will acctually happen. Litecon had halving just recently, and its price did not double.
