Come on guys, it's the simple market correction trying to stabilize the bitcoin price. Once the correction time is over the bitcoin price will grow even higher, bigger and better as well.
It is not a simple market correction - it is clearly well thought price manipulation from some whales. Drops like 20% aren't natural and are caused by highly coordinated market orders designed to trigger stop losses and cause more damage to price which will allow whales to accumulate even more...
