Ethereum Whale Rebuilds $19.5M Stack Amid ETF Outflows

Ethereum whale thomasg.eth is back — and buying hard. On-chain data published by Arkham Intelligence shows the wallet accumulated roughly $19.5 million worth of ETH over the past week, capping the run with a $3 million purchase on March 20. What makes the timing unusual isn't the size. It's that the wallet went on offense precisely when institutional money was heading for the exits.

The Whale That Held $537M Is Accumulating Again

Arkham's tracking shows thomasg.eth spread the position across spot ETH, wrapped ETH, and Aave-deposited ETH — a diversified on-chain stack rather than a single lump-sum bet. The wallet's buying strategy suggests deliberate accumulation over multiple days, not panic buying or a one-off move.

The wallet last commanded attention at the 2021 market peak, when Arkham estimated its total crypto holdings at roughly $537 million. Since then, Ethereum has pulled back sharply — 56% below its all-time high of $4,946, a peak reached on August 24, 2025, according to CoinGecko. From that lens, thomasg.eth is essentially rebuilding at a steep discount to where it once sat.

There's something worth noticing here: this wallet didn't just nibble. Seven figures across multiple vehicles — spot, wrapped, and DeFi-deposited — reads like someone who's done the math and decided the risk/reward flipped. Whether they're right is another question.

Why Buy Into Three Days of ETF Outflows?

This is the part the bullish headline misses. While thomasg.eth was accumulating, US spot Ether ETFs were bleeding. Data compiled by Farside Investors shows the funds recorded $55.7 million in net outflows on March 18, followed by $136.4 million on March 19 — the heaviest single-day exit of the stretch — and another $42 million on March 20. Three consecutive days, $234.1 million total out the door.

That's the institutional read on ETH right now: cautious at best, fleeing at worst. The Ether ETF outflows streak is a blunt signal that traditional finance allocators aren't rushing to add ETH exposure at current prices. thomasg.eth is swimming against that current.

Call it conviction. Call it contrarianism. Either way, the whale and the ETF crowd are looking at the same chart and drawing opposite conclusions — which, honestly, is what makes on-chain data worth following in the first place.

Tom Lee Makes the Bull Case for ETH — With Data From 1987

Enter Tom Lee, Fundstrat founder and current chair of Bitmine Immersion Technologies. Bitmine holds around 4.6 million ETH and has been accelerating purchases in recent weeks. Lee argued this week that the ETH bottom is effectively already in, leaning on analysis from technical analyst Tom DeMark.

DeMark's work shows ETH's recent price action carrying a 93% correlation with the S&P 500's recovery pattern after the 1987 crash and the 2011 bottom. The implication: Ethereum either found its floor around March 7 or is in the final stages of forming one right now.

Lee also pointed to ETH's realized price — the on-chain average cost basis across all holders — which currently sits at roughly $2,241. He noted that ETH was trading at a comparable discount to its realized price during major lows in 2022 and 2025, suggesting the current level fits a familiar bottoming pattern.

The historical return argument is striking. Over the past decade, according to Lee, ETH has returned roughly 49,000% — dwarfing Bitcoin's 11,000% over the same period and even outpacing Nvidia's famously parabolic run. He frames ETH as a "great store of value" despite its brutal drawdowns, arguing that the current pain fits the profile of a "mini-crypto winter" in its final stretch. The conviction behind that framing is why Bitmine Immersion Technologies accelerated its buying program rather than waiting.

ETH has returned roughly 49,000% over the past decade, far outpacing Bitcoin's 11,000% and even Nvidia's parabolic run.

What Does This Mean for ETH Holders Right Now?

Two major buyers — one anonymous on-chain whale, one publicly traded corporate treasury — are building ETH positions into a backdrop of institutional outflows and a price sitting more than halfway off its peak. If you're holding ETH, that's either reassuring or irrelevant depending on your time horizon.

The DeMark correlation argument is worth taking seriously but not uncritically. A 93% correlation with 1987 and 2011 recovery patterns sounds precise, but historical correlations in crypto have a habit of breaking down the moment everyone starts citing them. What's harder to dismiss is the realized price argument — ETH trading near or below its on-chain average cost basis has historically marked durable entry points, not just bounces.

The broader picture: smart money — or at least well-capitalized money — appears to be accumulating ETH at current levels. The ETF crowd isn't. That divergence rarely stays unresolved for long.
