Did people forget about how we reached the $9000 mark? It were $500-$1000 pumps that brought us there, and now we're going down by $500-$1000 dumps. Nothing to be shocked or surprised about.
It really seems that when the price has gone up no one cares about how it went up, but when we fall people come up with all sorts of theories mostly hinting at manipulation. This is what Bitcoin does. Get used to it.
Indeed, this is a decentralized market and you need to get used to price fluctuations. The fall was not so big and now, it seems, Bitcoin is starting to grow again in price. So, last night, its price, according to CoinMarketCap, was 7659 dollars, but now it has risen to 7879 dollars. So we will consider this as a normal bitcoin price correction.
