Theres a reason why Bitcoin was called a bubble..
I strongly believe Cryptocurrency will bounce back... but in a different form with a higher hash function than SHA-256 and probably strictly managed by some elements within the G8.
Bitcoin was a test but the world must still go fully digital in basic finance administration and other areas as well
And the increase in the number of bitcoin payment terminals is only an affirmation. So there is not only hope but also confidence that in five years everything will turn upside down and cryptocurrency will be everywhere.
