This month all prices of digital currencies have dropped dramatically, this is due to the large number of people who buy bitcoin and other currencies so the exchange rate decreases. The key is if you play treding you are patient, because it does not rule out the possibility of bitcoin will rise many times the previous price. When the price of bitcoin is falling dramatically as it is today, many bitcoin players will sell it so that there is no more loss. Usually bitcoin players with a lot of capital often sell so as not to lose more, after bitcoin players are competing to sell bitcoin, then the bitcoin exchange rate will be even higher, even able to rise up to 80% of the original price.
