Recently, the crypto assets market has experienced turmoil again. The LINK coin price has shown significant fluctuation in a short period, attracting high attention from investors.

Geopolitical factors have become an important catalyst for market fluctuations. The sudden escalation of tensions in the Middle East has led to a cautious investor sentiment, making the crypto assets market no exception. LINK plummeted 6.5% in one hour, reaching a critical support level of $17.408, forming what is referred to in the market as a 'black swan gap'.

Meanwhile, the Federal Reserve's monetary policy decisions have also become a key factor influencing the market direction. Although a 25 basis point rate cut is almost a certainty, investors are more concerned about the Fed's guidance on future policy direction. If the Federal Reserve fails to provide clear signals regarding potential rate cuts in December, the market may fall into a situation of 'good news fully priced in'.

From a technical perspective, LINK's trend presents a complex situation. The MACD indicator shows divergence, indicating potential downside risks, but at the same time, an initial golden cross signal has also appeared. However, the decrease in trading volume exposes the lack of bullish momentum. $18.231 has become the dividing line between bulls and bears, with the intraday high of $18.426 and the resistance level of $18.703 forming a key resistance zone for the rebound.

On the support side, buying resistance has emerged around $17.68, but trading volume remains low, indicating an unstable basis for the rebound. If this support level is broken, it could trigger a larger-scale sell-off.

For trading strategies, it is advised that investors remain cautious. Aggressive traders can establish defensive positions in the range of $17.68 to $17.75, and if it breaks above $18.231, they may consider chasing up to a target zone of $18.426. However, if it falls below the support of $17.408, one should be wary of a potential sharp decline, which could even test the lows near $17.00.

Overall, the current market is full of uncertainty, and investors should remain calm and avoid blind operations. Closely follow on-chain data and market dynamics, and make rational decisions based on your own risk tolerance, as this is the correct way to proceed steadily in this highly fluctuating market.
