March 2024 was a dynamic and eventful month for the cryptocurrency markets, characterized by significant price movements, regulatory developments, and technological advancements. Bitcoin and Ethereum led the way with substantial gains, while the broader ecosystem witnessed progress in scaling solutions, regulatory clarity, and emerging trends like memecoins and AI tokens.
Market Performance Overview
Bitcoin started March trading near $61,200 and concluded the period at approximately $71,300, marking a solid 17% increase for the month. The first two weeks saw strong upward momentum, largely driven by robust inflows into spot Bitcoin ETFs. Notably, March 12 recorded a remarkable $1 billion single-day inflow. However, momentum shifted mid-month as higher-than-expected inflation data pushed back expectations for Federal Reserve rate cuts, leading to stalled ETF flows and even a net outflow on March 18—the first in several weeks.
Throughout the remainder of March, Bitcoin's price reacted to macro-economic news and improving ETF flows toward month-end. Beyond market activity, several notable events occurred: Bitcoin's hash rate reached a record high, futures open interest hit new peaks, and the Lightning Network's USD capacity also achieved unprecedented levels.
Ethereum opened February around $3,350 and climbed 9% to finish near $3,650. While largely tracking Bitcoin's performance, Ethereum also navigated its successful Dencun upgrade, declining expectations for a near-term spot Ethereum ETF approval, and reports of a potential SEC investigation into whether ETH constitutes a security.
Ethereum's Dencun Upgrade and Scaling Progress
The Dencun upgrade, successfully implemented on March 13, represents one of Ethereum's most significant technical advancements since The Merge. Central to this upgrade was EIP-4844 (proto-danksharding), which introduces a new transaction type that carries "blobs" of data. This innovation dramatically reduces Layer 2 transaction fees by allowing rollups to post data via temporary data blobs instead of permanent call data, which historically constituted the majority of L2 costs.
Since Dencun's implementation, many Layer 2 networks have witnessed transaction fee reductions of 90% or more, making Ethereum ecosystem applications substantially more affordable to use. Beyond immediate fee reductions, EIP-4844 establishes the foundational architecture for Ethereum's long-term scaling roadmap, including full danksharding implementation.
The upgrade also included several other important EIPs that enhance Ethereum's functionality and efficiency, marking a critical step forward in the network's evolution toward greater scalability and usability.
ETF Developments and Regulatory Landscape
Spot Bitcoin ETF flows continued to significantly influence market dynamics throughout March. After strong initial inflows, the products experienced volatility with several days of negative flows in the second half of the month. This shift appeared driven by reduced inflows into the "Newborn Nine" ETFs (now ten with Hashdex's conversion to a spot ETF) alongside elevated outflows from GBTC.
Analysis suggests current ETF inflows are increasingly retail-driven, potentially making them more volatile and price-sensitive than earlier institutional-dominated flows. However, the market appears to be adjusting to this new dynamic with a lower correlation between flows and price movements.
The outlook for spot Ethereum ETFs appears less optimistic. Reports indicate minimal engagement from the SEC with potential issuers, contrasting sharply with the extensive discussions that preceded Bitcoin ETF approvals. Political pressure against further crypto ETF approvals has also emerged, exemplified by a letter from two U.S. Senators urging the SEC not to approve additional digital asset ETFs.
Additionally, reports of an SEC investigation into whether Ethereum constitutes a security have further dampened approval prospects. Market-implied probabilities of May approval have declined significantly, with prediction markets assigning just a 19% chance of approval by the end of May.
Regulatory Environment and Enforcement Actions
U.S. regulators remained highly active in the cryptocurrency space throughout March. Most notably, multiple reports indicated that the SEC has launched a formal investigation into Ethereum, potentially seeking to classify ETH as a security. This effort reportedly began in September 2022 following Ethereum's transition to proof-of-stake, which some speculate provided the SEC with new grounds for pursuing security classification.
In other regulatory developments, a judge denied most of Coinbase's motion to dismiss the SEC's lawsuit against the exchange, ruling that the SEC sufficiently pleaded that Coinbase operates as a clearing agency, broker, and exchange under federal law. However, the court granted Coinbase's claim that it doesn't act as an unregistered broker through its wallet service—a decision viewed positively for the DeFi ecosystem.
The SEC also sought a approximately $2 billion fine against Ripple Labs for unregistered XRP sales, settled with ShapeShift regarding allegations of selling unregistered securities, and settled with Genesis Global on charges related to Gemini Earn. In a separate case, the SEC was sanctioned by a court for "gross abuse of power" in its action against Debt Box.
The Department of Justice charged KuCoin and two founders with operating an unlicensed money-transmitting business and violating the Bank Secrecy Act, while the CFTC simultaneously sued KuCoin for operating an illegal digital asset derivatives exchange. Notably, the CFTC reiterated in its filing that Bitcoin, Ethereum, and Litecoin are commodities—a position potentially at odds with the SEC's approach.
Emerging Trends: Memecoins and AI Tokens
March witnessed explosive growth in memecoins, with established tokens like Dogecoin, Shiba Inu, and Pepe each gaining approximately 90% or more. Several smaller memecoins achieved even more dramatic returns, with some posting multiples of their previous values. This frenzy was particularly concentrated on high-throughput blockchains like Solana and Base, where increased activity led to network congestion and higher fees.
While some fundamental developments supported specific tokens—such as exchange listings, token burns, and product announcements—the primary driver appeared to be speculative fervor, exemplified by traders investing over $100 million into Solana-based memecoins during a single weekend.
AI-related tokens also performed strongly, likely bolstered by Nvidia's 14% monthly gain, a generally favorable crypto market backdrop, and several notable web3 AI developments. The most significant announcement was a proposed merger between Fetch.ai, SingularityNET, and Ocean Protocol to create a "Superintelligence Alliance" targeting artificial superintelligence development.
Additional AI-related developments included a $100 million infrastructure investment by Fetch.ai, dramatically increased Bittensor subnet registration costs, Tether's announcement of an AI initiative, and NEAR Protocol's presentation at Nvidia's annual AI conference alongside the impending release of NEAR Tasks.
