This volatile market also has some patterns. Since the beginning of this year, except for the breakthrough on March 5th which was a bit high, the 4-hour RSI(6) has basically started to decline whenever it approaches around 81. BTC could be at its peak or it might rise for a few more hours before reaching the peak. Yesterday was no exception.

However, there is no regularity at the bottom, so finding the oscillation peak and paying attention to when BTC starts to decline to open a short position is also a good idea.
