It is seen that Bitcoin, which increased its gains after sharp decline in the dollar index, lost momentum following the opening of the US session. Technically, Fibonacci 38 percent retracement line indicating 42 200 will be decisive to ensure the continuity of the purchases in the cryptocurrency. If BTC exceeds this level strongly, we will follow 43 250 and 44 400 resistance levels closely. On the other hand, 40 400 can be followed as a support in the possible downward movements of the day.
