Bitmine Immersion Technologies transferred about 9,600 ETH (≈$19.5 million) to Coinbase Prime hot wallets Transfers occurred in two separate transactions executed on Tuesday
Bitmine ETH transfers to Coinbase
Bitmine Immersion Technologies moved about 9,600 ETH (roughly $19.5 million) to Coinbase Prime hot wallets in two transactions of 5,300 ETH and 4,308 ETH.
“Bitmine Immersion Technologies moved about 9,600 ETH (roughly $19.5 million) to Coinbase Prime hot wallets in two transactions on Tuesday, per Arkham data: 5,300 ETH (~$10.75M) and 4,308 ETH (~$8.74M).”
Both transfers were routed through an intermediary wallet, a pattern observers say is typical of institutional custody flows, according to blockchain-tracking data reported by Arkham and multiple outlets.
Bitmine ETH purchases
The transfers come after Bitmine's largest weekly ether purchase of 2026 - 60,976 ETH - which lifted its holdings above 4.5 million ETH.
Company leadership framed continued buys as an opportunistic move during a downcycle, with Chairman Thomas Lee saying the firm is increasing purchases amid what it calls the 'final' or 'late stages of a mini-crypto winter.'
Context for ETH transfers
Industry analysts and blockchain observers emphasized that moving ETH into Coinbase Prime’s hot wallets does not necessarily signal an imminent sale. Such transfers commonly reflect institutional treasury management activities including custody, rebalancing, staking, collateral management, or preparing for OTC trades. Coinbase Prime’s operational hot wallets can hold assets without immediate liquidation.
“Moving coins to Coinbase Prime (Coinbase’s institutional custody/trading platform) does not necessarily signal a sale; it can reflect custody, rebalancing, staking, collateral management, or OTC preparation.”
Bitmine portfolio decline
The movements must be viewed against the backdrop of a substantial decline in Bitmine's portfolio valuation. Arkham-tracked data show Bitmine's wallet value peaked near $16 billion in October 2024 and fell to about $2.25 billion amid ether's price drop. That left the firm with estimated unrealized losses of roughly $7.8 billion, a factor analysts say helps explain active treasury management during this period.
