bitcoin daily 18. dec evidence

If the price falls below the blue arrow, it is proven that BTC is in a regression.
It will prove that the currently assumed blue wave 4 is wrong, since the price cannot fall below a wave 4 before completing a wave 5.

A price falling below the green arrow (which is the next support support level) cannot tell anything which is not clear already: that a green trend section has ended. It consists of the 3 lightblue trend sections.
