I see a lot of people saying, why is “second brother Ethereum” so weak?

Actually, if you look back at the start of this round of market momentum, it was pretty strong. It was completely dragged down by KelpDAO—because when it came to the DeFi protocol, it had been very strong from the beginning. After this incident, it just kept getting weaker and weaker. You could call this a “butterfly effect.” At first, everyone was just watching. Later, if you don’t buy, I don’t buy—so nobody buys.
Actually, there’s no real need to stubbornly fight for the rebound. This thing is just a soft target. Shorting is the preferred choice; going long requires careful consideration. After all, judging from its performance over a long period of time, it really isn’t as good as “big brother” Bitcoin.
It’s “second brother Ethereum” in name, but it has already moved away from the mainstream trend. Now it’s entirely about sentiment—when it goes up it doesn’t follow, and when it falls it drops even harder. In any case, the trend is pretty shady/copycat.
Unless there’s suddenly a wave of good news to stir things up emotionally, otherwise I guess things will be like this in the short term.
