At this point you should trade short, can see that bitcoin price fluctuations are hard to predict, although in the bull market, but I think this is only uptrend in the short term and the price of bitcoin may be more The downtrend is bearish for long-term price is still bearish. So if you trade at this point, you should get your profit back if you have one.
