I think this is not the thing to be worry about because I think we all should know that bitcoin is a decentralised crypto currency and moreover bitcoin is volatile in nature and a kind of investment so all these factors contribute a lot in flactuation in the valuation of bitcoin so ups and downs and pump and dumps are very common in bitcoin and this should not to worry about that much , though this time the valuation has deflated to a very low extent but still there are hopes that it will inflate again.
