BitMine Immersion Technologies Inc. (BMNR) shares took a beating on Monday as crypto-linked stocks retreated across the board. Bitcoin (BTC) slipped below $86,000, but it's Ethereum (ETH) weakness that's really hurting BitMine. That makes sense when you consider the company is the largest Ethereum holder in the world.

Why Ethereum Matters So Much to BitMine

BitMine's crypto strategy is all-in on Ethereum. As of November 30, the company held 3,726,499 ETH tokens valued at $3,008 per token on Coinbase. That's more than 3% of the entire ETH token supply, putting BitMine about two-thirds of the way toward its ambitious "Alchemy of 5%" goal.

When you're sitting on that much of one asset, price movements hit hard. Every dollar Ethereum drops translates to real pain for BitMine shareholders.

Doubling Down Before the Upgrade

Despite the recent volatility, BitMine has been aggressively adding to its Ethereum position. The company scooped up 96,798 ETH over the past week alone, pushing weekly purchases up by 39%.

The timing isn't random. Ethereum's Fusaka upgrade is set to activate on December 3, bringing improvements in scalability, security, and usability. Tom Lee of Fundstrat, who serves as BitMine's chairman, highlighted the upcoming milestone: "As we look ahead to December, the Fusaka upgrade, aka Fulu-Osaka, is scheduled for activation Dec. 3rd and delivers an array of improvements in scalability, enhanced security and usability."

The Crypto Treasury Rankings

BitMine holds the crown as the number one Ethereum treasury globally and ranks second among all crypto treasuries. The only company ahead of them is Strategy Inc. (STRF), which owns 649,870 BTC valued at $59 billion.

BitMine shares were down 11.86% at $29.19 at the time of publication on Monday, according to market data.
