On June 5, the price of Bitcoin once again reached above 70,000. The S zone has always held a bullish belief, but it is not suitable to chase now. There is limited room for further upward movement in the short term, and the risk of chasing is greater than closing. A head and shoulder bottom structure may be formed. At present, the construction time of the right shoulder is half of that of the left shoulder. The right shoulder is likely to be unfinished, and the possibility of continued correction is high. Therefore, it is not recommended to continue to trade above 70,000.
