Bitcoin's Short-Term Rebound Opportunity

After a sustained decline, Bitcoin here formed the first rebound opportunity, 4 hours macd formed a long trend, short-term look at this low once confirmed, there will be a strong rebound. But in the form of confirmation, there are about two movements, a, b, and the rebound target can be set at Fibonacci 0.5.
A, break back: up to break the moving average pressure, and then step back on fibonacci support level, second up break, is a good buy point
B, secondary bottoming: do not break through the pressure level, and then the second bottom, forming a macd bottom divergence, when macd form a secondary "golden cross", is the buy ingress point

Both of these paths are ideal rebound trends. But there is also the possibility of failure, because the big cycle is still the down cycle. The possibility of C is also present. So buy be sure to look for a "right signal" with a strong certainty, and it is best to have a multi-standard confirmation.

Strategy: a, b two kinds of rebound trend, should be superimposed on the moving average "buy signal", to have a clear buy point after the formation of the entry, and to set a good stop loss.
