As I said yesterday, although we are in a downtrend since November's top, at this moment Bitcoin can take a pause and correct some of the drop.
Also, I've mentioned 42500 as a support zone and that the cryptocurrency needs to stay above this zone in order to maintain this scenario intact.
At this moment we are exactly in this support and there is a high probability for a new leg up that can reach the former support now resistance at 46k
A buy here can also have a very good R:R, while a daily close under 42k would signal that the correction is over.
