The resistance for bitcoin is $19k or $20k.
There's currently no resistance nor support. Just because there is a formed graph related to resistance, it means we can consider it as a resistance level
($18,000 - $20,000). Bitcoin continues to break walls even as we speak that's why there's no even bottom or floor that can be considered today. In other words, people buy bitcoin not because of the price but for the positive speculation.
It does make sense that price $13,000 - $14,000 is considered as a testing wall
(support) if ever Bitcoin price suddenly loses the momentum at around the current price and from there, the fuel is ready to make another journey to the new ATH.
But of course, since we are positive, we like to see Bitcoin reaching another ATH with no such thing as a sudden dip that will happen first. But to lessen the expectation, we should also consider other results that might not favor us.
