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
In any case, cryptocurrencies will be able to restore their high positions with time, now you just need to be patient. It must be remembered that the market is cyclical. After a long fall in prices, the bull run has to come, so I regularly invest money in the purchase of BTC.
