When trading markets its always a good question to ask who are you buying from and who is selling and with big moves, why they always come to an end with either a pull back or counter trend rally if oversold.
Bitcoin is currently in short term looking like the buyers are in retreat and the sellers about to take over the reigns.

Short term Bitcoin looks over brought in my opinion and set to fall in short run.
Wishing you every success, health wealth and prosperity.
