Strategy (MSTR) shares rose 13% to $104.72, Bitmine Immersion Technologies (BMNR) climbed 13% to $20.63, and Coinbase (COIN) gained 11% to $162.88 midday Wednesday, marking the sharpest one-day pop for these crypto-linked equities this summer. The rally comes as Bitcoin (BTC) surged past $68,000 for the first time in months, possibly boosted by the U.S. SEC's proposed new cryptocurrency-related rules, known as “Regulation Crypto Assets.” Goldman Sachs nearly quadrupled its MSTR stake to $555 million.
