Bitcoin- Dive after overnight spike up?

Like EurUsd, Gold, and other assets, Bitcoin also had an overnight spike. However, this was anemic and very short-lived and after rising above the 20k zone we find Btc trading again at the 19700 zone at the time of writing.
As I said in my yesterday's analysis, I expect a break of 19500 support and a dive to the support given by the previous low.
Negation of this outlook comes with a daily close above 20.500 resistance.
