The price is going up like 200 in 30 min, happens often and then it drops even harder like -400, can someone explain to me why this happens? I always know when its going up fast within the next hour it drops even harder....

The price is going up of more 300 in half an hour because a lot of trader are considering the support line at 2500 .
We was at this "support line" and all these traders are now affraid for this price raise and wants to be in, nor out : they put massive buy orders to be in (because after this support, Bitcoin can going over his previous resistance price" of 4100 ).
