Relax!
in 2013 bitcoin was $1045 and in January 2015 bitcoin has seen $207!
We are seeing the same problem right now. Bitcoin has fallen 80 percent! just 3 years ago.
Bitcoin will rise again. It takes time to see another bull run.
Bitcoin might see $4000 and it is totally normal.
If you compare 2013 and 2017, the chart is almost the same.
Yes, events like this have happened and we should not worry because conditions can be so fleeting. Now there is a dumping of Bitcoin prices and it is possible that at the beginning of next month we can see positive price movements. For example what happened in 2014. Now we must have a high sense of optimism, whatever happens we must try to think positively and hope that the price of Bitcoin can return to a good phase.
