According to Crypto Rover (@rovercrc), ETH broke above $4,300, signaling an upside breakout (source: Crypto Rover on X, Aug 11, 2025). Traders now eye the 2021 all-time high near $4,867 as the next major resistance and potential profit-taking zone (source: CoinMarketCap ETH historical price data showing Nov 2021 ATH around $4,867). The $4,300 level may act as first support on any retest given the breakout principle where former resistance can become support (source: Edwards and Magee, Technical Analysis of Stock Trends). Round numbers such as $4,500 often concentrate orders and can create interim resistance or acceleration once cleared (source: Edwards and Magee, Technical Analysis of Stock Trends). Breakout failure risk remains; failed moves frequently retrace to or below the breakout level before finding demand (source: Edwards and Magee, Technical Analysis of Stock Trends).

According to @KobeissiLetter, Ethereum (ETH) rose about 7% on Saturday night to around $4,300, its highest level since December 2021 (source: @KobeissiLetter). The post also highlighted broad market strength with the comment that crypto is on fire, underscoring bullish momentum across digital assets (source: @KobeissiLetter). Based on the reported move, traders may monitor $4,300 as a near-term breakout pivot for continuation or a retest zone for risk management in ETH-USD (source: @KobeissiLetter).
