Ethereum has periodically challenged Bitcoin's dominance, starting with its 2015 launch, which introduced smart contracts and a programmable blockchain, sparking speculation about its broader utility. By 2017, the ICO boom highlighted Ethereum's potential for token creation and fundraising, with ETH reaching $757 against Bitcoin's $13,880. The 2020 DeFi boom further positioned Ethereum as a revenue-generating platform, contrasting with Bitcoin's static holdings. In 2021, the NFT craze showcased Ethereum's role in digital ownership, with ETH prices soaring to $3,682. The 2022 shift to Proof-of-Stake, known as "The Merge," made Ethereum deflationary and yield-bearing, enhancing its appeal over Bitcoin. In 2024, the introduction of ETH ETFs and treasury allocations emphasized Ethereum's programmable nature, while 2025 saw favorable policies from the Trump administration, fueling narratives of Ethereum's potential to outperform Bitcoin, with ETH reaching $4,200 compared to Bitcoin's $116,700.
