Yesterday Bitcoin established support from the 1D 200EMA at $42.2K, it formed a double bottom at the hourly chart. This could indicate the bottom or a reversal. However today, the reversal is challenged by the resistance from 3D 50EMA at $45.8K, it just formed a double top. It seems that the area between $42.2K and $45.8K will be range where bulls and bears will fight today.
