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
Cryptocurrencies are called a bubble primarily because of their unreasonable price increase. See how the market for the year fell in price? Is it really not possible to call the bubble blown away?
