I can't really understand why Bitcoin fluctates fast, even it will goes up or down. Is it because there are too many miners nowadays? or the supply and demand of services through Bitcoins. The only thing that I understand is it has a really great value compare to Fiat money.
Well, it is simply beacuse some people would like to keep their position invested in bitcoin and others would want to cash out at this stage. It is all about people's expectations - if satoshi is found, then it is likely to drive up the price.
If a big newspaper says that bitcoin will go down, then it will likely to be going down.
