Stop trying to attribute every single price movement to some underlying event.
Sometimes corrections simply happen because of chance. A position might be closed by a whale, which triggers some arbitrary TA signal, leading to an adjustment without any external shock.
The market is overwhelmingly bullish still, and these bearish episodes should be short lived so long as institutional investors continue to pile in from all directions.
Bitcoin's price fluctuation is a normal situation as supply and demand are always determining factor. Speculation may not be stopped, but we know that institutional investor are the strongest proponent that price will not fall on a large scale. We can even see it dropping by up to 20% in one period, but the market will recover as soon as the trader panic subside. The FUD will affect people and a wave of panic will inevitably arise when they believe that news can affect the price. But in fact, bitcoin has been trusted and has great support and is getting stronger as a long-term investment asset.
