Ethereum Price Breaks $4,200
Strength in the ETH/BTC pair has extended to Ethereum’s dollar value. On August 9, ETH/USDT broke through $4,080 and quickly climbed to $4,220, a level last seen in December 2021. The biggest push came in a one-hour jump of nearly $140, with prices closing near $4,174.

In the days leading up to the surge, Ethereum had been building momentum from the $3,800 range, recording higher highs and higher lows. Bitcoin, on the other hand, traded in a narrow range, making Ethereum move into a leadership position. Stockmoney Lizards pointed to a breakout on the 4-hour ETH/BTC chart, a setup often seen before broader altcoin rallies.
Eyes on Potential Altseason
With ETH/BTC now holding above both short-term and long-term resistance, attention is shifting to altcoins. A move toward 0.0400 BTC could align with Ethereum reaching $5,000 if Bitcoin’s price remains near $125,000.
Trading activity has been supported by increased buying volume and signs of whale accumulation. As long as Ethereum maintains levels above 0.035 BTC and $4,000, conditions remain favorable for continued strength and potentially the start of a larger altcoin rally.
