And what is exactly the ground for such claim?
I can't see any. To my opinion this is a pure speculation that could only bring panic among users and this is the last thing we need. The price is moving around 8000$ for a while now and I don't think some biger changes will happen in any way, so I don't expect some biger fall but not also some biger rise.
Speculators getting at it again, just to scare the living daylight out of investors and make them withdraw their money so that price will go down to an affordable rate for them to buy as much as they can afford. Im not buying such lies, although the price is not showing any sign of improvement lately, but no matter what the price must still go up, so I will continue to have patience.
