Next Strong Resistance of BTC

Analysing support and resistance is helpful for us to find better entry and exit, so how to determine the next strong resistance for Bitcoin after a big jump ?

Attach the Fibonacci retracement tool on the highest top (64854) of Bitcoin's price history and drag it to the lowest bottom(28805) in the past few month, as you can see in the figure above, there is a 0.618 resistance at $51083.

I will close my long position before reaching $51000 and short BTC at the same time.
