Big Bitcoin suddenly dropped this morning, breaking through the triangle pattern and hitting new lows. However, after creating the new low, it didn't continue falling. Instead, it formed a hammer line, indicating there's buying support below. This drop looks more like a washout, clearing out the trailing long positions below.

Why did Big Bitcoin suddenly drop? Because there's strong resistance near 71974 above, and two attempts to break through failed. Each high is lower than the previous one. Unable to go up, it can only find support below, attracting bottom-fishing capital to enter. Next, focus on whether it can return above 69222. Holding steady here would end the decline, with oscillation expected in the 69222-70400 range. Breaking through 70400 could challenge the 71505 resistance again.

Operations: $BTC Big Bitcoin long at 68500-68780, targets 68900-71250, if breakout then look at 71250-71500.
Resistance levels: 69371, 70507, 71355; Support levels: 68752, 68188, 67293.

Ethereum similarly weakened, breaking through the flag pattern with 2127 as short-term resistance. Returning inside the flag pattern is needed to halt the decline. Breaking out of the flag could attempt to charge toward 2202. If it can't hold 2105, it will test the 2046 low, with increased downside risk if broken.

$ETH Ethereum operations: Long at 2060-2085, targets around 2125, if breakout then look at 2176-2205.
Resistance levels: 2106, 2142, 2176; Support levels: 2097, 2067, 2036.

Overall, both major cryptocurrencies showed no continuation after the sharp drop. Key levels will determine the subsequent trend. Watch for breakout and breakdown signals in operations, with strict risk management.
