🟠 $BTC + 🔵 $ETH + 🟡 $SOL | 15M 📊 $BTC is currently leading with clean momentum, $ETH is steadily catching up, while $SOL is pressing hard against its range high. 🧠 The key signal is SOL: if buyers break through with volume, liquidity could rotate across altcoins and ignite a full risk-on expansion. ⚠️ If SOL rejects here, BTC and ETH strength may stay contained and the market could cool into consolidation. 🔥 BTC leads + ETH confirms + SOL breaks = explosive market expansion.$BTC
