Bitcoin dropped sharply, losing over 30% from its mid-October peak to below $85,000, erasing more than $750 billion in value and triggering further steep declines in Ethereum, XRP, Solana, and Dogecoin as well as crypto-related stocks such as Coinbase Global, Robinhood Markets, and Riot Platforms.Strategy, founded by Michael Saylor and holding nearly 650,000 Bitcoin, saw its share price drop while revising its price forecast downward and raising $1.44 billion, with Patrick Horsman and Christoffer De Geer offering warnings on further downside risk and expressing long-term optimism despite steep declines.Crypto markets face additional pressures from interest rate speculation, heightened by the Bank of Japan and upcoming Federal Reserve decisions, as Donald Trump, Donald Trump Jr., Eric Trump, and affiliated ventures such as American Bitcoin and World Liberty Financial suffer heavy losses, and regulatory uncertainty continues despite Trump signing stablecoin protection regulations in July.
