It happen so quickly, its was 7,989 USD and when I refresh the page in less than a minute the price dives to 7,600USD already.
This was as always one whale selling lots of coins in a matter of minutes and plummeting the price.
Hopefully he buys back soon :-)
He must have seen the price will drop very soon. I have noticed it also that when BTC doesn't break out after two weeks, the higher the possibility that price will dive. But I hope this whale will learn the weirdest way possible if some whale counter part intentionally burn him.
