Bitcoin rocketed from 14K straight to 16K where it found resistance. Een retrace is coming. And don't under estimate these retraces. They can go fast with a quick drop of -20/30%. These retraces have taken place more often in the past. Try not to short Bitcoin, but rather buy it at each dip. A new ATH is upcoming.
To buy I look around the support zone: 12500 - 11500 Also Weekly EMA 21 is a reliable support/buy zone in an uptrend.
