Ethereum at the Crossroads: A Full Research Analysis Following the Spot ETF Launch

Let's start with a distinction that matters more than most coverage acknowledges. Ethereum and Ether are not the same thing. Ethereum is the blockchain platform - a decentralised global computer capable of running self-executing contracts and hosting applications. Ether (ETH) is the native currency of that platform, the fuel that makes it run. When someone says they're "investing in Ethereum," they almost certainly mean they're buying ETH - but understanding why ETH has value requires understanding what happens on the platform it powers.

The most useful mental model we've encountered for Ethereum is that of a global computing platform with its own native currency. Think of it less like a payment network and more like an open-source app store, where every interaction - every smart contract execution, every trade on a decentralised exchange, every NFT transfer - requires a payment in ETH. The more the platform is used, the more demand there is for ETH. That's the core of the investment thesis.

Where this gets complicated is in evaluating just how much the platform is actually being used, and whether that usage is growing in meaningful ways. We'll come to that when we look at the on-chain data. But first, it's worth mapping the main application categories clearly, because the framing matters for how you assess Ethereum's long-term potential.

There is no shortage of breathless content about Ethereum's "limitless applications". Most of it conflates technologies with applications, overstates adoption, and buries the lead. In the interest of clarity, here are the four use cases we believe are materially real and relevant to the investment case right now.

The most technically significant development of the past twelve months for Ethereum was the Dencun upgrade, which went live on the Ethereum mainnet in March 2024. Understanding what it did - and what tradeoff it created - is important for evaluating the current supply dynamics around ETH.

The centrepiece of Dencun was a mechanism called proto-danksharding. In simple terms, it introduced a new type of data storage on the blockchain called "blobs" - temporary data bundles that layer-2 networks can use to post transaction records to Ethereum without permanently occupying the main chain's storage. Because this data can be deleted after approximately 18 days rather than living on the blockchain forever, it takes up far less space per transaction. Less storage consumed per transaction means lower fees.

The tradeoff is straightforward: lower fees mean users transact more - and Ethereum's layer-2 networks have confirmed this empirically, with Arbitrum doubling its daily transaction volume and Base reaching over three million transactions in a day. But lower fees also mean less ETH is burned per transaction, which has shifted Ethereum's supply from mildly deflationary to mildly inflationary. The net annual inflation rate since Dencun is less than 1% - lower than gold or silver - and stakers can offset it entirely through the ~2.5% annual staking yield available even through centralised platforms like Coinbase.

We do not view this as a negative development. The Dencun upgrade is an acceleration of adoption: it made Ethereum materially cheaper to use, and the usage data confirms people responded. The slight reduction in ETH's scarcity economics is a reasonable price for a platform that is actually growing. The supply narrative was never what made Ethereum interesting anyway.

We are strong believers in reading on-chain data before forming a conviction. Ethereum's blockchain is fully transparent - every transaction is publicly recorded and analysable. Here is an honest reading of what the key metrics show heading into August 2024.

The picture that emerges from this data is genuinely mixed. Layer-1 daily transactions have flatlined at around 1–1.5 million since 2021 - a level they reached during the DeFi boom of 2020 and have not materially exceeded since. Active wallet addresses similarly sit in a range of 250,000 to 500,000 without clear upward momentum. If you evaluate Ethereum purely on this layer-1 usage data, the story looks like a platform that has not grown meaningfully in years.

The more optimistic - and we believe more accurate - reading is that layer-2 networks represent the real growth vector. The Dencun upgrade was explicitly designed to make L2 usage cheaper, and the March 2024 data confirms that it worked. The question is whether L2 growth will eventually translate into more demand for ETH itself as the settlement layer beneath it.

On July 23, 2024, spot Ethereum ETFs began trading on U.S. exchanges. It was the biggest regulatory milestone for Ethereum since the SEC's surprise approval of the Bitcoin ETFs in January of the same year. For context: Bitcoin ETFs averaged $100 million in daily net inflows and helped stabilise Bitcoin's price during episodes of sell pressure, including the German government's multi-billion dollar BTC liquidation in July, which was absorbed by ETF demand within three weeks.

The key question for Ethereum is how large the institutional demand will be relative to the Bitcoin precedent. We have one data point worth anchoring to: existing global institutional demand for Ethereum-related exchange-traded products (excluding U.S. spot ETFs) runs at approximately 31% of the comparable Bitcoin demand. Galaxy Research has applied this ratio to the ~$17 billion in Bitcoin ETF inflows recorded in the first six months of trading to project roughly $10.5 billion in annual Ethereum ETF inflows - or about $900 million per month.

We view this as a reasonable base case, not a certainty. What we are more confident about is the structural mechanism: the ETFs create a new, permanent channel of demand from institutional investors and retail investors using brokerage accounts where buying ETH directly is either operationally cumbersome or prohibited. Pantera Capital disclosed a $100 million seed investment in the Bitwise spot Ethereum ETF - an early signal that sophisticated crypto-native capital sees this access channel as meaningful.

There is one short-term overhang worth acknowledging. The Grayscale Ethereum Trust (ETHE) held approximately 2.63 million ETH - worth roughly $9.6 billion - at the time of ETF conversion. Investors who bought ETHE when it traded at a 24% discount to NAV in April will likely take profits at par now. This potential early selling pressure from ETHE redemptions is the primary near-term risk to the ETF launch narrative, and it is the reason we are not calling this a trade to size aggressively at the moment of ETF debut.

Ethereum's supply mechanics are more complex than Bitcoin's, and this complexity is frequently misunderstood in both bullish and bearish directions. Let us walk through how ETH supply actually works.

The transition from Proof of Work to Proof of Stake in September 2022 - known as "the Merge" - reduced new ETH issuance by approximately 90%. Combined with the EIP-1559 burn mechanism introduced in 2021, this has been described by advocates as Ethereum's "triple halving." Unlike Bitcoin's mechanically fixed halving every four years, Ethereum's supply dynamics are demand-responsive - which makes them harder to model but also means the asset benefits directly from network usage in a way Bitcoin does not.

One practical implication for ETF investors: U.S. spot Ethereum ETFs are not permitted to stake the ETH they hold. This means ETF holders will not receive the staking yield - roughly 4–5% annualised - that direct ETH holders or liquid staking protocol participants can access. For investors who prioritise yield, direct ownership via a liquid staking service like Lido is superior to an ETF from a return-per-unit-of-risk perspective. For investors who prioritise simplicity, regulatory clarity, and accessibility within existing brokerage infrastructure, the ETF is the right vehicle.

We are asked frequently whether investors should choose Bitcoin or Ethereum for crypto exposure. Our answer is that it is the wrong question. These are different assets with fundamentally different investment theses, and conflating them leads to poor allocation decisions.

BlackRock's Jay Jacobs framed it well: Bitcoin's value proposition lies in its simplicity and credibility as a non-sovereign monetary instrument. Ethereum's appeal is its flexibility and potential to underpin a wide range of decentralised applications. These are complementary assets, not competing ones. A portfolio that holds both is making two distinct bets - one on money, one on the internet's next computing layer.

The ETH/BTC price ratio has drifted lower since the Merge in September 2022, meaning Bitcoin has outperformed Ethereum in relative terms over that period. Historically, extended periods of Bitcoin outperformance have been followed by Ethereum catching up - and often overshooting. The upcoming spot ETF launch, the Dencun fee reduction, and Ethereum's significantly undervalued position relative to its 2022 highs may collectively set up that rotation. But we would not bet the farm on a specific timeline.

No analysis of Ethereum is complete without addressing the perennial narrative that a newer, faster, cheaper blockchain will eventually displace it. Solana is the most prominent current candidate for that label, having significantly outperformed Ethereum in price terms since the Dencun upgrade and attracting attention for its high throughput and lower fees.

Our view: Solana is a serious, well-built platform. We use it. But we do not believe it displaces Ethereum as the dominant smart contract platform, for three interconnected reasons.

First, Ethereum's developer community is by far the largest in blockchain. The number of active developer teams building on Ethereum's core protocol and application layer dwarfs that of any competitor. This creates a compounding advantage: better tooling, faster security auditing, and a richer ecosystem of composable building blocks that new projects can leverage. Solana cannot replicate this with capital or marketing - it requires years of organic developer adoption.

Second, DeFi TVL and dApp volume data confirm that Ethereum's lead in actual economic activity is massive. Ethereum's 30-day dApp volume exceeds that of the next closest layer-1 chain by a factor of more than ten. When real money is deployed into financial applications, it predominantly goes to Ethereum.

Third - and the lesson of a decade of crypto markets - every blockchain tagged as an "Ethereum killer" has eventually either pivoted, stalled, or imploded. EOS, Cardano, TRON, and Terra were each briefly framed as likely successors. Solana is a better-engineered competitor than any of them, but the pattern of hype around the label should make investors cautious about the framing itself.

That said, we take competition seriously as a risk and we have included it explicitly in our risk register below. Ethereum's lead is large, but it is not permanent. The trilemma - decentralisation, security, scalability - remains unsolved at Ethereum's current scale. The continued upgrade roadmap is the main mechanism by which Ethereum maintains its competitive advantage over time.

We hold a position in ETH. We are biased in a bullish direction and we know it. The discipline of this section is to force us to articulate, as honestly as possible, the ways in which this bet could lose significantly. Investors should weight these risks carefully before sizing any allocation.

Vitalik Buterin's publicly published roadmap for Ethereum is unusually transparent for a global technology platform. Understanding the phases matters because each represents a potential catalyst for both utility and investor sentiment.

• Completed - September 2022: The Merge

  Transition from Proof of Work to Proof of Stake. Reduced energy consumption by ~99.95%, cut new ETH issuance by ~90%, and laid the foundation for all subsequent upgrades. Created the "triple halving" supply dynamic.
• Completed - March 2024: The Dencun Upgrade

  Introduced proto-danksharding (EIP-4844), reducing layer-2 transaction fees by up to 88%. Launched "The Surge" phase of Vitalik's roadmap, focused on scalability through rollup-centric architecture. Arbitrum and Base transaction volumes immediately spiked.
• Upcoming: EigenLayer Restaking

  Restaking allows smaller blockchains and applications to leverage Ethereum's security without building their own validator sets. EigenLayer is pioneering this. As more services adopt restaking, demand for ETH as economic collateral increases. Currently early-stage but growing rapidly.
• Upcoming: Gas-Free Stablecoin Transactions

  Planned integration would enable fee-less USDC transfers on Ethereum, directly competing with PayPal USD and Coinbase/Circle's USDC product. If implemented, removes one of the largest practical barriers to Ethereum-based payments at scale.
• Future: Full Danksharding and The Scourge / The Verge

  Full sharding will massively increase data availability, enabling significantly higher L2 throughput. Subsequent upgrades focus on validator decentralisation and statelessness - reducing hardware requirements for running nodes and making the network more censorship-resistant.
