How can we do next about bitcoin?

Hi everyone, I start to share my idea again.
After a sharp rise, the pattern started a flag. During the Flag, I prefer a market reversal. How high is the bounce going to be? I can't sure right now, but please pay attention the resistance level.
At which point will the market reverse? I prefer the price will re-test the support level again.

If the price re-test the support level, we still have to figure out if it is going to reverse.
First Case: It maybe a V shaped reversal. If it happened, long the bitcoin, pay attention the resistance level.
Second case: There is no V shaped reversal. The price start a congestion area.
Picture A: Low point gets more higher. The price will go up, long bitcoin.
Picture B: Horizontal price movement. The price will break blow the resistance level, short bitcoin.

Thank you.
