The crypto market has suffered a heavy blow today, waking up to find that prices have plummeted significantly. This market is characterized by drastic fluctuations, and for ordinary investors, the asymmetry of information makes it extremely difficult to achieve profits. Israel's raid on Iran is a prime example; such unpredictable political events often have a huge impact on the market.

In this fluctuating environment, position management is particularly important and is key to avoiding liquidation.

In terms of Bitcoin, a strong daily bearish bar was formed today, breaking through multiple daily support levels, and the bullish pattern has been destroyed. A technical rebound may occur in the short term, with the primary resistance level for the intraday rebound around 105,000. If this level is broken, attention can be turned to the 106,000 area. If today's small-scale rebound fails to break through 105,000, the market may further decline to the 102,600 or even 101,000 area, where these positions may provide better entry opportunities for long positions.

Ethereum performed similarly weak today. Although it briefly found support at 2,615 in the morning session, it then sharply dropped by more than 100 points, breaking the daily chart pattern. The key resistance level for intraday rebound is 2,570, and if it breaks through, attention can turn to 2,644. If it fails to break 2,570, the strength of the rebound may be limited, and there is a risk of re-testing the lows at 2,545 or 2,380. It is recommended to wait for a second dip before considering entering a long position.

Solana has directly dropped to the daily support level near 141, with a significant pullback. In the short term, attention can be paid to the rebound situation, with important resistance levels at 148 and 153. Near the second resistance level, it may be worth considering a defensive short position. If it can drop again to around 140, a small position can be attempted for a rebound, but it is essential to set a stop loss.

Regarding Binance Coin, if it tests near 640 again, you can try to set up a rebound opportunity, with a stop loss set at the previous low. The intraday rebound resistance level is at 656, and after breaking through, you can pay attention to the 661 area. These resistance zones are also potential short positioning locations.

Overall, the current market is in a stage of high uncertainty, and investors should remain cautious, strictly control their positions, and manage risks effectively.
