BTCUSD is a buy now. The price has been retesting the lower boundary of the channel and now it's ready to continue the uptrend.
We can see that it's a potential higher low which is a sign that the uptrend is still in tack.
As long a 21350$ holds, BTC has a chance to continue the uptrend.
Target: upper boundary of the channel
Daily close below 21350 $ would be an invalidation of the thesis and then we should see more downside.
Good luck
