Recently, Ethereum (ETH) has been performing remarkably, encountering strong resistance around the $4000 mark. Throughout this week, ETH has attempted multiple times to break through this key level, but has not succeeded.

Despite this, market analysts remain optimistic about the future trend of ETH. It is generally believed that there is still a significant possibility for ETH to break through and stabilize above $4000. Once this psychological barrier is breached, ETH will set a new historical high, which could trigger a wave of widespread market sentiment, especially impacting other cryptocurrencies (commonly referred to as "altcoins").

Many observers predict that if ETH successfully breaks through its historical high, it is likely to drive a general rise in the entire cryptocurrency market, especially small-cap tokens which may see significant increases. This phenomenon is known in the cryptocurrency market as the "FOMO" (fear of missing out) effect.

For investors, this may be a period worth paying attention to. Medium- to long-term investors may consider continuing to hold or increase their spot positions, while short-term traders may be more inclined to look for opportunities in the contract market.

It is worth noting that the Federal Reserve's interest rate decisions are also one of the important factors affecting the cryptocurrency market. Investors should closely monitor relevant policy trends, as they may have a significant impact on market movements.

Overall, the current market environment is full of opportunities as well as risks. Investors should develop appropriate strategies based on their risk tolerance and investment goals, and always remain vigilant, keeping an eye on market dynamics.
