Trading is certainly an art more than a science. It takes a lot of intuition and cunning to excel no matter what the asset. With something so volatile as BTC, there is plenty of opportunity to profit...and lose.
I am a HODL and just use pullbacks to add. My timing in the market sucks.
As for the $600 jump, it is amazing what you can get use to. A 20% pullback in BTC is nothing...if it happened to a stock it would be all over CNBC.
Interesting point you make there, Bitcoin volatility is actually getting closer and closer to that off a stock. 600 is only ~10% at these levels, 10% is a pretty normal day in the equity markets.
