Ethereum price breaks out, hits 2-month high versus Bitcoin — is the rally sustainable?

The rally has pushed ETH price toward strong resistance levels, increasing its pullback risks against Bitcoin.

Ethereum’s native token Ether (ETH) has successfully avoided a bearish technical setup to reach a two-month high against Bitcoin (BTC).

ETH price bear flag invalidated

The ETH/BTC pair invalidated its prevailing “bear flag” pattern after Ethereum developers announced this July 14 that their long-awaited switch to proof-of-stake (called the Merge) will most likely occur in September.

ETH/BTC has rallied by more than 22% since the announcement, reaching 0.067, its highest level since May 25. Furthermore, the pair’s sharp upside move has pushed its net retracement gains to 37% when measured from June 13’s local bottom of 0.049.

Ether tests key inflection zone

Strong fundamentals led by the Merge launch could have ETH/BTC pursue a run-up toward the 0.072–0.076 area. This range was instrumental as resistance in January and March–May. Therefore, it should serve as the next upside target for Ether bulls.

But there’s a catch. Notably, ETH/BTC has been showing signs of a weakening upside momentum near what appears to be a strong resistance confluence. 

That includes a falling trendline resistance, a Fibonacci retracement line (near 0.066 BTC), and a support-turned-resistance area (the 0.064-0.068 BTC range), as shown below.

In addition, ETH/BTC’s daily relative strength index, a momentum oscillator indicator, has crossed into so-called “overbought” territory, suggesting elevated risks of a sell-off.

Independent market analyst “Altcoin Sherpa” cited a similar technical setup this July 18, noting that the ongoing ETH/BTC rally could be “unsustainable.”

In other words, ETH/BTC could see a reversal toward 0.06 by September if the inflection resistance zone holds for a 9.5% decline. The 0.06 BTC level also coincides with the 0.236 Fib line, as shown in the chart above.
