A ~$500k USD buy annihilated the $200 wall. Yes, there was resistance. However, resistance was futile.
There must be some big buyers entering the game, wonder who they are? Do you think someone eg the FED may buy up a whole load of bitcoins to ramp the price up. Then sell really quickly to try and cause crash?
Who knows. By those standards I'd be a "big buyer." And since I'm definitely not... who knows. I highly, highly doubt anybody with the necessary resources would be using them to seesaw the price.
They might hope to seesaw the price to persuade people its too volatile to be serious as a currency. If I was the PTB I'd be trying to control it first before trying to clamp down on it. Clamping down would be last resort.
