maybe that makes the price of bitcoin on this exchange place fall back because of the bad news circulating and maybe also because many countries don't want to accept bitcoin as one of their payments.
In my opinion there are many factors which cause the falling price but we should not be panic and should be cool and patience in this time. bitcoin investment is not for short time and to make money from bitcoin we will have to wait for long time. market manipulation is the main reason for downing price of bitcoin. Low demand and low mining also cause low price.
