BTC 4th wave (ZIGZAG formation)

We are currently in wave 4, what looks to be the formation of a ZigZag (ABC). I count 4 subwaves in A, so i presume a little more downside in the coming hours (5th subwave) before starting the B wave that would bring us back about 50% of wave A. Then C wave (5 subwaves) to finish the 4th wave. After completion of the 4th wave. I look to long BTC as I believe the 5th wave of higher degree will bring us some relative good gains. The target for the 5th wave is still unclear to me as it can be an expanded flat correction or running flat.
