No doubt there has been some heavy manipulation by large bitcoin holders. The problem is the weak hands panicking & following the whales by selling.
The whales will be laughing as they gobble up coins now at a 20% discount to what we were at a week ago.
The whales are the ones that lead every dump and pump.
When they dump, we shouldn't be too concerned about how things are going for bitcoin because that's their decision, and it doesn't reflect what the community thinks about bitcoin in general. It doesn't prove anything if bitcoin price is low.
Similarly, if price is high, doesn't mean everything is going well for bitcoin.
If bitcoin drops to $800 I would buy a bunch as well, just like BitcoinBarrell. I doubt that will happen though... I feel like a short squeeze might be coming soon.
