As we can see, Bitcoin can probably find support at the bottom of wave 2, as happened in the previous pattern. This pattern repetition could be giving rise to a huge triangle. The decrease in volume may be pointing to high volatility soon, as it happened at the end of wave C. If you use fibo, you will find the same points... but since it's Bitcoin, we can't expect anything. It can simply break out and start a bullish or bearish rally. Hope this helps.
