$BTC 1. The current price is $1,553.28, showing a weak oscillation pattern throughout the day. It dropped from a high of $1,816.38 to $1,410 (a decrease of about 22.3%), with a limited rebound (rising only to around $1,553), indicating that the bullish momentum is weaker than that of Bitcoin. MA7 (1,544.23) and MA30 (1,504.67) also formed a golden cross, but the price is close to the MA7, and we need to be cautious, as a drop below the MA7 could trigger a second bottom test.

2. Key support levels: MA7 (1,544) MA30 (1,505) previous low (1,410). Resistance: whole number level of $1,600 - $1,700 (previously dense trading area). Bitcoin's range is targeted around 78600-79000 for short positions, near 77000.
