ETH/BTC is maintaining its position above the ascending trendline—a bullish sign for now. Here's what matters: if this pair fails to break above 0.0309, ETH won't be outperforming BTC in the near term. And when that happens, you can expect the entire altcoin market to struggle. This level is critical. Watch it closely. The chart tells the story—whether altcoins rally or retreat depends on ETH's performance relative to Bitcoin.
