Early trading BTC strongly advances, reaching a high of 81,999, just one step away from 82,000!

It was then met with obvious selling pressure.
On the four-hour chart, the overall upward channel remains intact, and the high-level oscillation seems more like a way to digest profit-taking.
In the medium term, it is still viewed as oscillating with a bullish bias; as long as the core support zone of 79,500 - 80,000 is maintained, there is still a possibility of a short-term surge again to 82,000 - 83,500.
The volatility range is relatively large, so defensive awareness must be maintained, but before the trend clearly weakens, backtesting support is an opportunity for low buy-ins, not blindly shorting.
From the 15-minute analysis from early morning until now, Bitcoin shows a typical pattern of a sharp rise followed by a pullback, with high-level oscillation:
Early strong breakout and surge, reaching around 81,999;
Followed by a stepwise decline.
Currently, the basis is slightly discounted, green bars are shortening, red bars' momentum has slowed, and the price is in the process of searching for a secondary bottom support.
