Bitmine Immersion Technologies, the Ethereum (ETH) treasury firm chaired by Fundstrat's Tom Lee, has reportedly added another $145 million worth of ether to its holdings on Tuesday, showing no signs of easing its accumulation.

Onchain analytics provider Lookonchain, citing Arkham data, reported that Bitmine purchased 67,111 ETH worth roughly $144.8 million from Kraken on Tuesday via two addresses. Another analytics platform, EmberCN, also flagged the transactions.

The reported purchase today adds to Bitmine's holdings of 4.66 million ETH ($10 billion) recorded as of March 22, representing around 3.86% of Ethereum's current circulating supply. The company said in a Monday disclosure that it had acquired 65,341 ETH since its previous update on March 16.

The Block has reached out to Bitmine for further information.

"Bitmine has maintained the increased pace of ETH buys in each of the past three weeks, as our base case is ETH is in the final stages of the 'mini-crypto winter,'" Tom Lee, chairman of Bitmine, said in the Monday statement.
