Bitcoin fell sharply this morning, breaking through the triangle pattern and creating a new low. However, after hitting the new low, it didn't continue falling but instead formed a hammer candlestick, indicating there's buying support below. This decline appears more like a washout, clearing out retail long positions following the trend.

Why did Bitcoin suddenly drop? Because there's strong resistance around 71974 above. Two attempts to break through failed, with each high lower than the last. Unable to go up, it can only seek support below, attracting bargain-hunting capital to enter. Next, the focus is on whether it can return above 69222. If it stabilizes here, the decline ends and it will oscillate in the 69222-70400 range. Breaking through 70400 could potentially challenge the 71505 resistance again.

Trading strategy: $BTC Bitcoin 68500-68780 longs, targets 68900-71250, if breakthrough, watch 71250-71500.
Resistance levels: 69371、70507、71355; Support levels: 68752、68188、67293.

Ethereum is similarly weak, breaking through the flag pattern with 2127 as short-term resistance. Only re-entering the flag pattern can stop the decline, and breaking above the flag could challenge 2202. If 2105 doesn't hold, it will test the 2046 low, with increased downside risk.

$ETH Ethereum strategy: 2060-2085 longs, targets around 2125, if breakthrough, watch 2176-2205.
Resistance levels: 2106、2142、2176; Support levels: 2097、2067、2036.

Overall, after both major coins' sharp decline, there's no continuation. Key levels will determine subsequent price action. Focus on breakthrough and breakdown signals in operations, with strict risk control.
