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
If we look at the charts of falls and rises of BTC, we'll understand why it's considered to be a bubble. In comparison with other bubbles, BTC has already inflated and collapsed 3 times. So cryptocurrencies have their own unique way of development!
