April 20 Bitcoin Market Analysis: Trading at high levels with pressure leading to a correction, the overall trend has not reversed. The daily chart still remains above the medium- and long-term moving averages, and the bullish pattern remains intact. This pullback is more of a normal correction during an upward trend, with no clear reversal signals. The four-hour chart shows a short-term decline after a rally, with key support concentrated around the 73,500-74,000 range. Holding this support could lead to a rebound.
