The Ethereum/Bitcoin rivalry is real, according to Tom Lee, chairman of BitMine and co-founder of Fundstrat. Lee, a key Ethereum stakeholder whose market influence stems from his institutional investments and public advocacy, claims that ETH can reach $60,000 in five years and has a 50% chance of flipping Bitcoin. However, while Ether has been performing undoubtedly well this past summer, topping Bitcoin is a hot take. Summary After the immensely bullish summer for Ether, the âETH will flip BTCâ narrative is back. Ethereum flipped Bitcoin in spot ETF inflows and demonstrates consistent growth. Despite Etherâs success, it must reckon with Bitcoinâs status and so-called âEthereum killers.â Crypto influencers tend to argue, on X, that Ethereum earns extra praise when Bitcoin is down. A closer comparison between the two cryptocurrencies show that, in the long run, Ethereum is gradually going down against Bitcoin. Ether was at its peak price against BTC in February 2018 at 0.13 BTC per Ether. In the spring and the fall of 2021, when Bitcoin was trending higher, the peak Ether prices were in the 0.08â0.09 BTC range. Fast-forward to 2025: at 0.04 BTC per ETH, one Ether is worth 4 million sats â fewer than before. In other words, after the spring of 2021, Etherâs price saw no serious spikes against Bitcoin. The ETH/BTC price chart | Source: TradingView While Ether has gained price against Bitcoin since April â its price rising from 0.019 to 0.04 â in BTC terms, each unit of ETH is cheaper than it was in 2021 or 2017. Therefore, despite Etherâs current price of $4,280 (a 92.5% rally from last year), Bitcoin maintains its position as the dominant cryptocurrency. As Jeff Embry of Globe 3 Capital put it: âETH has too high a hill to climb to surpass BTC, and the drivers of what creates value for both should keep BTC in the lead.â Ether competition Spot ETFs for Ether rivals are on the horizon, and treasury holdings in other digital assets could challenge Etherâs dominance. For example, Tronâs low-cost transactions may gain traction as stablecoins expand. While Ether could outpace Bitcoin, it remains far below its 2017 highs, and its uncapped supply limits its potential to surpass Bitcoin. Leeâs bold predictions come as BitMine Immersion Technology (BMNR) strategically shifts its focus to building a large Ethereum treasury. Meanwhile, Michael Saylorâs Bitcoin-focused Strategy is facing challenges, having been recently sued by investors and snubbed from the S&P 500. Ethereum: the bullish case As of Sept. 6, Bitcoinâs market cap is over $2.2 trillion. Etherâs market cap is $515 billion. But, in April, the market cap of Ether was below $180 billion, so it grew considerably in the summer months. Ethereum co-founder Joseph Lubin says itâs only a matter of time before his brand of crypto closes the gap. âETH will likely 100x from here,â he posted to X on Aug. 30. âProbably much more.â Ethereum co-founder Joseph Lubin hinted on CNBC that he believes $ETH could flip $BTC within âthe next year or so, especially with these treasury companies driving things.âAt bitcoinâs current market cap, ETH would need to be around $20,000 to flip it. pic.twitter.com/o3730nEmCYâ Satoshi Stacker (@StackerSatoshi) August 10, 2025 Before June, Ether struggled amid criticism of large sales by the Ethereum Foundation, which contributed to price declines. Solana eventually surpassed Ethereum as a leading platform for memecoins. And this past spring, ETH was trading below $2,000. https://twitter.com/MitchellHODL/status/1906033607094780277 By July, Ether gained over 60% while Bitcoin gained only around 10%. Ethereum dominance doubled between May and August, going from 7% to 14%. The summer of 2025 saw a lot of factors contributing to Etherâs bull run: BitMineâs Ether pivot. Massive Ether ETF inflows and intensifying stablecoin race. The European Union plans to use Ethereum for a digital euro. Under Lee, BitMine Immersion Technology turned into the second-biggest digital asset treasury in the world and the top corporate ETH holder. As of Aug. 25, it owns 1.71 million Ether units. The company aims to buy 5% of the Ether supply. At the current stage, it owns nearly a third of the needed amount. Lee isnât the only one who cares about BitMineâs success. Big-name investors like Peter Thiel, Cathie Wood, and Bill Miller III now hold large stakes in the company. The company announced its plans to issue $20 billion worth of BMNR stock to raise capital for further increase of ETH holdings. ETFs Spot Ethereum ETFs have outpaced Bitcoin ETFs, signaling strong institutional demand. In July, Ethereum ETFs saw $1.8 billion in inflows versus $70 million for Bitcoin ETFs. This surge in 2025 followed Circleâs successful IPO, the GENIUS Act enabling stablecoin issuance, and growing stablecoin competition, with Ethereum supporting roughly half of the stablecoin market. On Aug. 22, the European Central Bank reportedly considered using Ethereum and Solana to issue a digital euro, potentially placing Ethereum at the core of a major economy. That same day, Fed Chair Jerome Powellâs Jackson Hole remarks hinted at a possible September rate cut, boosting liquidity. Combined, these developments propelled Ether near $5,000 for the first time on Aug. 29. Institutional investors are draining the Ether supply while drastically increasing demand for it. The amount of ETH held on exchanges has reached the lowest point in around ten years. These factors may contribute to the ETH price ascension.Â
