BTC continue to fluctuate in the channel.

BTC's current trend is adjusted back after a short-term decline, testing that there is a strong support line in 18943. The price returns to the channel, and the previous breakthrough is confirmed to be false, so we adjusted the overall upward channel. The 0.5 line segment of Fib Retracement and MA20 have suppressed the price, and the estimated price will drop to the 0.618 line segment of Fib Retracement and continue to fluctuate in the channel.
