Ethereum and Bitcoin have trading pairs, and their price directions are mostly aligned. So, trading Ethereum can indeed be more profitable, but it's also more volatile. This leads to some issues: first, it's easy to hit stop-losses; second, it's easy to get shaken out of positions. The benefit is that short-term trading feels comfortable, providing quick feedback—holding positions for just a few hours can yield significant gains. If you want to ride trends, Bitcoin is still the better choice. Mainstream coins like Ethereum and Solana can be held, along with platform tokens like BNB and GT. During a bull market, these coins tend to lead the rally. As for other coins, they often drop 99% or more. The crash on October 11 showed that these four coins have strong defenses. We should focus on these for spot trading, while for futures, it's best to concentrate on Bitcoin.
