The BTC market is unpredictable in the short term, but longer term the obvious patterns form. If you are a long term bull, then trade on the long term patterns. Buy/accumulate when the market is bottomed and no one cares, sell near top of rallies. Then be patient to get back in, because a rally bubble can take a while to unwind. A LONG while. There may even be several mini bull runs/short squeezes along the way, but ultimately the price ends up bottoming out way lower and all volume/volatility dies.
How about this as a strategy for a lazy trader (like me)? It's the cross-overs of K and J of the KDJ indicator.

Yeah, these indicators are great for telling traders what has already happened.....
Look back to Sept 30th 2013. Bitcoin was just above $100, we had the Silk Road crash, and the Weekly KDJ was pointing DOWN! Probably, at the time, the KDJ was right on the point of crossover, except Bitcoin then shot up to $1200, and the lagging KDJ indicator took a slight little turn up again, for just a short time, as Bitcoin went up by over 1000%.
In otherwords, a fucking terrible indicator to be using in isolation.
Well I must say...
I think Torque is close...and The mad cat in da hat has made some interesting posts!
