Bitcoin is known for its volatility. There nothing crazy about it. Historically Bitcoin has been more volatile than what it did on Nov 12th. If you go back and check the price of Bitcoin for the last two years, it has outperformed.
The current price of Bitcoin is $8800. If you. Heck the price in the last two years it was:
2018 12th of Nov - $6371
2017 12th of Nov - $5950.
There is an increase of $2850 if I consider the price of 2017. Therefore everything is going in the right direction. Stay positive..
I differ from this comparison. BTC is too much volatile and year to year comparison is not justified. On 18 Dec 2017, price of BTC was 19000 USD while on 18 Dec 2018 it was 3780 USD.
