Bitcoin surged to 90799.90 yesterday and then started to pull back. It is currently oscillating repeatedly around 90300. In the short term, the 90350-90400 zone constitutes a support floor. Once broken through, attention should be paid to the performance of the 90000 key level; above, 90600-90700 is the resistance zone during rebounds.

From a technical perspective, MA7 has crossed below MA30 forming a death cross, with both moving averages pointing downward and price trading below the moving average lines, making the bearish pattern quite clear. Recent candlesticks are predominantly bearish, and although there was a technical rebound in the early morning, it was merely a recovery from oversold conditions with no signs of trend reversal.

On the operational level, if the rebound to around 90600 fails to break through effectively, consider opening a small short position with stop loss set above 90750. If the support at 90350 is breached, follow the downtrend and look toward 90000. Weekend trading is expected to maintain a oscillation pattern, with high selling and low buying being the main strategy. Ethereum and Binance Coin show similar trends, so be mindful of the risk of synchronized declines.
