these types of change don't really have to have any reasons they are just market fluctuations. you blink and 2% change happens, that is just how the market is.
This is simply wrong. Look at the market for yourself. I am talking about SUDDEN jumps. And in the past 8 days, there have only been 3 sudden jumps. Two drops and one surge. And each jump had a specific news event tied to it.
that would require the traders to be sitting behind their computers and refreshing all the news websites continuously and as soon as an article is published take action based on it! which is obviously not realistic. these sudden jumps are simply the market reacting to some rise/fall or it is even possible that a big order went through. for example currently price is $6630 and if someone sells about 50
BTC it will reach $6600 in one sweep and that will cause a bigger follow up drop where others sell and you suddenly see 200
BTC is sold after that leading the price down to $6490 which is about 2% drop. just like that...
