You haven't seen shit yet. Even a rise of 200$ followed by a fall by 300$ before rising again 400$ in 24 hours is a perfectly normal market action at times of super bullish price discovery. Until the rally lasts it will always recover and conquer even greater heights. Every time it crashes like that could be the final time but we will never know. For example, we might run up to 10000$ per BTC, then fall down to 6000$ temporarily, only to capture 17777$ the next day. The swings will get bigger as the climax gets closer.
