Based on my 4 year following of bitcoin, the M2 to bitcoin price correlation is definitely the most compeling one. I'll try to find some charts and get back to you.
Discussion
It seems very compelling! Going back and applying a few rules of selling or buying BTC based on percent changes in M2 the correlation held consistent for most moves. But I probably would get wrecked still. Im interested in discussing what you have decided is a good percentage change, or rate of change, or other metric of the M2 to justify that a local top or bottom is in for BTC?
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.
