I don't know much about why the price of bitcoin down,which only I know is possible, which makes the price of bitcoin dropped is because the enthusiasts of bitcoin is already not much more not like in 2017,I also think the price dropped bitcoi recently caused by the high number of people are cashing in bitcoin for a particular celebration. Moreover, the surge in the number of users of the newbie who are easily frightened by the decline in prices and therefore attractive investment at the time of decline in the value of bitcoin. As well as high levels of volatility are also to blame.
