21 800 support, which coincides with the Fibonacci 38.2% correction level, is critical for Bitcoin, which we have fallen under the ascending channel. It may be possible for the leading cryptocurrency, which is able to deepen its losses in a permanence that can be achieved under this region, to test 20 760 and 19 740 supports. However, BTC, which will turn to the test of the bullish channel in the persistence above the Fibonacci 38.2 level, may test the 23 300 level.
