$BTC playing with 4h 50 EMA, decision time
50 EMA seems pretty reliable in the case of predicting BTC move in clear strong trend (after inspection of past price and 50 EMA relation). My move would be : If 
BTC 4h closes under the 50 EMA (blue area) I close my long and I go short using fib retracement as target.
