In my opinion, there has to be some serious significant factor occurrence to cause that spikes. The chips have been really down for a while.
So if there are no factors to make you profit - you wont be buying bitcoin?
Most users think like that and they are the ones who will complain when the prices go back up again. True the prices are down but that means it is in the bear cycle trend and the cycle will go back with time which is where we should sell to get the profit+capital back.
It is not that everyday there needs to be a reason for the price to go up or down. If there is - good for us, if there is none - keep holding through the cycle.
Pro traders dont look for events, they look at the prices as numbers and buy/sell accordingly.
