2021 was a monumental year for Ethereum, marked by significant technical upgrades, soaring adoption, and dramatic market movements. From record-breaking price highs to groundbreaking network improvements, Ethereum solidified its position as a leading force in the cryptocurrency space. This article revisits the key moments that defined Ethereum's journey through 2021.
January: A Strong Start
The year began with Ethereum priced at approximately $738, holding around 11% of the total cryptocurrency market share. In contrast, Bitcoin dominated with 69%. Ethereum's decentralized finance (DeFi) protocols had over $16 billion in total value locked (TVL), signaling early growth potential.
Despite skepticism from traditional financial leaders—such as the Bank of England's Andrew Bailey, who expressed concerns about Bitcoin's longevity—Ethereum surged. By mid-January, it nearly broke its previous all-time high (ATH), reaching $1,345.98. Elon Musk's addition of #Bitcoin to his Twitter profile further fueled market optimism, pushing ETH to a new ATH of $1,428.94.
February: Institutional Interest and New Highs
February witnessed increased institutional interest. Tesla's disclosure of a $1.5 billion Bitcoin purchase positively impacted the entire crypto market. Ethereum benefited, consecutively setting new ATHs of $1,815.96 and $1,869.52. Major players like Mastercard and PayPal announced plans to integrate crypto services, while CME Group launched Ethereum futures, enhancing market accessibility.
ETH surpassed $2,000 for the first time on February 20, reaching $2,036.29. Although it corrected to around $1,400 by month-end, the stage was set for further growth.
March: Technical Upgrades and Mainstream Attention
March was a pivotal month for Ethereum. The Berlin hard fork launched on the Ropsten testnet, aiming to optimize gas fees. Amazon Web Services (AWS) announced support for Ethereum nodes, allowing users to deploy them easily via its Managed Blockchain service. This endorsement from a tech giant boosted Ethereum's credibility and network traffic.
ETH's price climbed from $1,469.73 to $1,933.04 between March 5 and 13. DeFi TVL on Ethereum surged to $42 billion, a 162.5% increase since January. Visa's pilot program accepting USDC payments via Ethereum highlighted growing corporate adoption. However, the sale of Beeple's "5000 Days" NFT for $69 million (42,329 ETH) at Christie's auction captured global media attention, showcasing Ethereum's cultural impact.
April: Investments and Hard Forks
April saw Ethereum reach new heights. On April 3, ETH hit $2,143.23, the first of many ATHs that month. A $65 million investment in ConsenSys—founded by Ethereum co-founder Joseph Lubin—by Mastercard, UBS, and JPMorgan signaled strong institutional confidence. ConsenSys, known for MetaMask, plays a crucial role in Ethereum's ecosystem.
The Berlin hard fork went live on the Ethereum mainnet on April 15, introducing new transaction types and adjusting gas fees. Although a technical milestone, it was a precursor to the more significant London hard fork. The Coinbase IPO further buoyed sentiment, with ETH crossing $2,500 and setting new ATHs of $2,534.41 and $2,613.91. By month-end, Ethereum's market cap exceeded $250 billion.
May: Volatility and Environmental Concerns
May started strongly, with ETH surpassing $3,000 on May 3 and peaking at $4,330.75 on May 12—a 60% surge in nine days. Euphoria swept the community, with predictions of ETH reaching $30,000 or higher. However, volatility struck when Elon Musk announced Tesla would suspend Bitcoin payments due to environmental concerns, impacting the entire market.
ETH plummeted to $1,857.64 by May 23 but recovered to $2,625 by month-end. Despite the downturn, Ethereum's DeFi TVL exceeded $93 billion, a 400% increase since January. Uniswap and MakerDAO led the DeFi space with $9 billion and $16.7 billion in TVL, respectively.
June: Mainstream Moves and Market Dips
El Salvador's historic decision to adopt Bitcoin as legal tender dominated June headlines, highlighting crypto's growing mainstream acceptance. However, Ethereum faced challenges. ETH dropped from $2,878.71 to $1,773.40, and DeFi TVL fell 31% to $64 billion. Criticism from former U.S. President Donald Trump, who called Bitcoin a "scam," added to the negativity.
Despite this, ETH rebounded to $2,251 by June-end, maintaining a 200% year-to-date gain—outperforming Bitcoin's 17%.
July: Regulatory Pressures and Recovery
China's intensified crypto crackdown dampened July's mood. Bitcoin mining operations shut down, causing BTC to drop below $30,000. Ethereum followed, bottoming at $1,738.76 on July 20. However, positive developments emerged: Jack Dorsey announced a new Bitcoin platform, and German regulators allowed institutions to hold up to 20% of assets in crypto.
ETH recovered to $2,536.46 by July-end, demonstrating resilience amid regulatory uncertainty.
August: Stability and the London Hard Fork
August brought stability and technical progress. ETH rose from $2,481.97 to $3,322.21, supported by PayPal enabling UK crypto transactions and Google allowing crypto ads. El Salvador's preparations for Bitcoin adoption continued.
The London hard fork went live on August 5, implementing EIP-1559—a major upgrade that introduced a base fee (burned) and priority fee (to miners). This reduced ETH supply, making it deflationary. Over $1 billion in ETH was burned within six weeks. The upgrade also paved the way for Ethereum 2.0's proof-of-stake transition. ETH fluctuated between $2,900 and $3,400, ending August at $3,433.
September: Market Shifts and Competition
September started positively, with ETH nearing $3,900. Ethereum's market share reached 20%, double its January level, while Bitcoin's dominance fell to 40%. DeFi TVL surpassed $90 billion. El Salvador officially adopted Bitcoin as legal tender, though it faced public protests.
China's ban on all crypto transactions triggered a market downturn. ETH dropped to $3,275, and competitors like Solana surged, rising from $35 to $210. ETH ended September at $2,974.24.
October: Optimism and New All-Time Highs
Rumors of Amazon exploring crypto sparked optimism, as did the SEC's approval of Bitcoin futures ETFs. Mark Cuban declared himself an "Ethereum maxi," praising its utility and smart contracts. ETH started October below $3,000 but rallied to a new ATH of $4,445.23 by month-end.
November: Milestones and Regulatory Challenges
Ethereum achieved new milestones in November. DeFi TVL hit $122 billion, a 660% year-to-date increase. ETH reached ATHs of $4,844.15 and $4,891.70, while Bitcoin peaked at $68,789. However, the U.S. infrastructure bill—mandating crypto tax reporting—and India's potential crypto ban caused volatility. ETH dipped below $4,000 but recovered to $4,650 by month-end. Global crypto markets nearly hit $3 trillion in capitalization.
December: Year-End Reflections
December proved challenging. Concerns over the Omicron variant and broader market pressures pushed ETH down to $3,632.56. It struggled to maintain $4,000, ending the year below expectations. Despite this, Ethereum's yearly performance remained impressive: a 450% price increase, doubled market share, and DeFi TVL nearing $120 billion.
