Bitcoin Whale Rotates $3.8B Into Ethereum, Analysts Call It a Sign of Market Maturity

Bitcoin Whale Swaps BTC for ETH in Massive Rotation

A long-time Bitcoin holder, known in on-chain circles as a “Bitcoin OG,” has shifted a significant portion of their fortune into Ethereum (ETH) during a weekend buying spree.

According to blockchain analytics firm Lookonchain, the whale sold 4,000 BTC worth about $435 million, and purchased 96,859 ETH over a 12-hour period.

The move builds on a trend that began on August 25, when analysts first noticed the whale rotating out of Bitcoin. To date, the entity has accumulated $3.8 billion in ETH while still holding over 100,000 BTC (valued at more than $11.4 billion).

On Monday, the whale deposited another 1,000 BTC into decentralized exchange Hyperliquid, suggesting further Ether purchases may follow.

Analysts: From Bitcoin Maximalism to Market Maturity

Industry experts see the whale’s rotation as part of a broader trend toward diversification.

Henrik Andersson, CIO of Apollo Crypto, noted that crypto cycles often see rotations from Bitcoin into Ether, and then into altcoins:

“After the GENIUS bill and pro-U.S. regulations, there is more gravity behind Ethereum. Some whales may be diversifying in light of this positive backdrop.”

The GENIUS Act, signed into law by President Donald Trump in July, represents the first U.S. federal legislation on stablecoins, creating momentum around regulated digital assets.

Ethereum has also been gaining strength in market performance. The token hit a new all-time high of $4,946 on August 24, according to CoinGecko, before cooling to $4,389 at press time.

Ethereum’s Yield and Utility Attract Bitcoin Veterans

For some Bitcoin holders, the move isn’t about abandoning BTC but rather recognizing Ethereum’s unique role in the evolving crypto economy.

Ryan McMillin, CIO of Merkle Tree Capital, explained:

“Many OG whales view Bitcoin as digital gold, while Ether offers yield via staking and exposure to the broader smart contract economy.”

He added that this rotation reflects a maturing digital asset ecosystem, where Bitcoin serves as a store of value, but Ethereum is seen as infrastructure powering DeFi, NFTs, and smart contracts.

Could Altseason Be Next?

McMillin also suggested that the whale’s move could be part of a classic altseason rotation — where capital flows from Bitcoin into Ether and eventually into other leading altcoins.

“If the ETH rotation gathers momentum, it wouldn’t be surprising to see flows extend into Solana (SOL) next, given its growing traction in consumer apps and DeFi.”

With Bitcoin trading sideways for months and Ethereum capturing institutional flows — including ETF demand in August — analysts believe capital rotations could continue shaping the market in the coming months.

Conclusion: A Turning Point for Crypto Allocations

The Bitcoin OG’s $3.8 billion Ether bet signals more than just a portfolio shuffle — it highlights a growing recognition among whales that crypto is no longer a one-asset market.

As regulatory clarity improves and Ethereum strengthens its position in both DeFi and real-world adoption, more long-term Bitcoin holders may diversify, solidifying ETH’s status as a core crypto holding alongside BTC.
