BMNR fell more than 11.8% to $35.11 and is now down some 74% since spiking to $135 early this month.

BitMine has positioned itself as one of the largest corporate accumulators of ether in recent months, amassing more than 300,000 ETH worth over $1 billion.

Numerous companies have adopted a strategy of building an Ethereum treasury, copying the playbook of Michael Saylor's Strategy (MSTR) with bitcoin.

Among other factors, this has helped ignite a breakout in ETH's price, which has gained around 57% in July to almost $3,900, according to CoinDesk data.

ARK also sold just under $7 million of Coinbase (COIN) shares and $15 million worth of Jack Dorsey's fintech company Block (XYZ), based on Monday's closing prices.

Small investors are buying bitcoin. For a rally to succeed, the whales need to join in.

A tiny dollar bill held between thumb and forefinger

Small wallets have increased their BTC holdings by 2.5% since October's all-time high while large holders trimmed 0.8%, Santiment data shows.

Lo que debes saber:

  • Bitcoin wallets holding less than 0.1 BTC have increased their share of supply to the highest since mid-2024 even as the price holds around the mid-$60,000s.
  • Larger holders with 10 to 10,000 bitcoins — the whales and sharks that typically drive major moves — have reduced their positions since the October peak.
  • The divergence supports choppy, fragile price action because retail demand alone cannot sustain rallies when big wallets are distributing into every recovery.
