The 42100 remains as the main support. The previous 50% line (43300 level) now becomes as the prevailing support. Price is currently facing resistance in the 44K level. In this setup, if BTC closed above the bullish line, it is likely that BTC will break the resistance and then attempts to reach the 45K level. However, if the resistance is too strong, BTC is likely to test again the prevailing support. A retest of the 42K support is also possible.
The path to 50K is highly probable if BTC breaks the 45K level. It is not happening soon but that depends on the volume of buyers.
