I think the factors that affect bitcoin is the volume of the investors and also with a positive and negative news. I believe that possitive news is really the most amazing factors that can make the price rise up high, because the trust is really important on bitcoin and some good or maybe bad news will reflect on the different kinds of investors and this was maybe the factors that affect the price.
Gone are the days when news would lead sharp spikes in prices. Big players are now in the game and are now profiting out of gulible traders. For example in the recent deep, Can you point out to me the bad news that led to the sudden deep in price? 😒
