Bitmine Ethereum Withdrawal From Kraken: $144.7M Custody Shift

Onchain Lens reported that Bitmine executed a large Ethereum exchange withdrawal from Kraken on March 15, 2025. Two newly created addresses received 67,111 ETH, worth about $144.73M at the time. This Ethereum exchange withdrawal is notable because it reduces immediately tradable ETH on centralized exchanges and typically signals a move toward controlled custody rather than near-term selling. Analysts highlighted transaction details consistent with planning: standard network fees (no rush), batch execution instead of a single transfer, and fresh destination addresses with no prior activity. After the move, Bitmine reportedly controls about 4.6M ETH across custody wallets, roughly 3.8% of Ethereum’s circulating supply—making it one of the largest single holders. The article contrasts this with Lido DAO’s estimated 9.2M ETH holdings (though Lido is framed as staking-service/pooled exposure) and other institutional holders. Security and compliance themes also featured in the coverage. The article cites best-practice custody measures (multi-signature wallets, HSMs, geographically distributed key storage) and links the withdrawal timing to regulatory maturation in the EU (MiCA, fully implemented Dec 2024) and ongoing US SEC guidance. Trading relevance: an Ethereum exchange withdrawal of this size can temporarily tighten exchange liquidity and add short-term volatility risk for smaller traders. Longer term, sustained exchange outflows can support a bullish supply/demand backdrop if demand remains steady. However, correlation isn’t causation—watch whether exchange balances continue falling and whether derivatives positioning confirms the move.
