January 21st Bitcoin/Ethereum Technical Overview

Bitcoin's performance on the 4-hour chart is quite interesting—after bouncing off the lower Bollinger Band, it has stabilized. The KDJ indicator has turned upward from the oversold zone, with the J line crossing above the K and D lines, indicating a clear bullish crossover at a low level. This suggests that the short-term rebound momentum is building. The Bollinger Bands are also narrowing, indicating decreasing volatility, with prices beginning to recover around the lower band. The key now is whether it can break through the critical resistance level at 92,000.

Ethereum is stabilizing in sync with Bitcoin, and the correlated movement is quite evident. The short-term rebound opportunity has already appeared.

Simple trading ideas:
BTC can consider going long in the range of 88,300-88,800, with the first target at 2,980. If a strong breakout occurs, it can continue to look toward 92,000.
ETH can be followed around 2,900-2,930, with the first target at 2,980. If broken, continue to watch for 3,050.
