It seems that what makes the bitcoin price drop quickly is the frantic bitcoin owners looking at the market. They will definitely throw away or sell bitcoins at the most expensive price to sell quickly because they are afraid bitcoin can not go back up.
I thinkit is not rapidly going down to this prior matter. The rate is just affected by some factors that is happening the market and it is completely normal for bitcoin to low down its price. Bitcoin is a bubble but it gives us a lot of financial benefits that it alone can satisfy our daily needs and also our wants. It is a good investment because of it's good rate that is underrated by many investors that wants fast profit.
