Update on BTC analysis: First, the daily chart has basically topped out already, and the probability of breaking through the 78,300 high again is very low because the high point on the daily chart touched the EMA moving average resistance level, and was subsequently pushed down. Last night, both the weekly and daily charts closed; the daily chart closed with two consecutive bearish candles, and the gains from the previous bullish candle have almost been wiped out. Additionally, the weekly chart shows a long upper shadow, which is enough to confirm the top signal is valid.
