Absolutely No. Although the the value of Bitcoin cryptocurrency have been crashing lately, there no cause for alarm. Even comparing the price of bitcoin for this year, 2018 to the previous years bitcoin price still stand tall or it is higher. I think that recent decline in price is as a result of the hikes. well, just like any other business or market there are risks which are unforseen and can happen at any time. So risk when occur should not stop you from persueing your business. just get encouraged and work towards solving the problem. In any event, there are predictions that bitcoin will rise to 100000 USD this year. More hope!
