How true is the price of bitcoin repeat it in history. Have you also observed it or it may be coincident only. If that so, this will be expected to happens in this year?
As far as what i understand on the previous chart of bitcoin, starting from the last 5 years is that bitcoin moves in the same pattern with growing price. Right now it shows the same pattern and could possibly surpass the past years in terms of price. So it is better to be patient in holding your bitcoin and stop panic selling your stocks.
