In the stillness of the K-line chart, undercurrents are surging! Bitcoin firmly clings to the 84800 level, repeatedly testing in the fog of the trend channel (upper band 85854, lower band 82363).

What kind of grand strategy is the market playing? Remember, before the fog clears and the upper band defense line is breached, any impulsiveness may fall into a trap!
