According to Miles Deutscher, the key trigger for Ethereum is a decisive break above its prior all-time high near 4,800, which he says is when the real fun for ETH begins (source: Miles Deutscher on X, Aug 12, 2025). He adds that the final explosive leg for altcoins tends to start only when ETH is close to its cycle high, anchoring altseason timing to ETH’s late-cycle strength (source: Miles Deutscher on X, Aug 12, 2025). For traders, this frames 4,800 as the primary ETH breakout level to monitor, with broader altcoin positioning more favorable as ETH nears its cycle top per his view (source: Miles Deutscher on X, Aug 12, 2025).
