After reading multiple books and watching countless hours of videos on trading, I learned that trading is hard as fuck, and I am by no means smart enough to do it, so I just dollar cost average all the time like a freaking maniac, with some dry powder on the side for market break-downs like the current one. I do, however, punt a leverage long here and there, based on technical analysis, which has been semi-successful for me so far. I do not like to sell my BTC, so I almost never do, at least not any real ammount. I might be willing to sell a small portion if the price went unsustainably parabolic in a short period of time.
