If BTCUSD can't break that yellow downtrend line, it could go back to the first support and form a head & shoulders formation. When that happens, expect for BTC to go down to the reversal levels indicated in the chart above.
However, if BTC goes up and breaks the downtrend trendline, it could retest the all time high and could probably make another all time high.
Watch the volume and price action in the coming hours within the day. Currently, I see that the volume is decreasing. But, a buying rally could occur and volume starts going up.
Just be on the lookout for BTC's movements. It's difficult to say where we will go next.
