I think the market experienced a fall like this maybe it happened because of the bad news that finally made many traders panic and made them sell all assets owned at cheap prices and make the exchange place collapse.
If they sold all their coin so they did bad to their own self as holding can give good profit than selling at panic. So before making investment with bitcoin better if one makes his own mind get positive about crypto currency price rise and fall, buy when you see price getting down and sell when you see price getting high, so now price is not high so golden chance to make investment with bitcoin and buy more coin so your income will be more than double within few months.
