Strategy (MSTR) should stop buying bitcoin BTC$62,634.53, rebuild its cash reserve and become far more disciplined about when it buys, onchain analytics firm CryptoQuant said in a Wednesday report shared with CoinDesk. The strain showing up in the company's STRC preferred stock is a sign the firm has overextended itself, it added. STRC, Strategy's flagship preferred stock, fell to about $82.50 last week, a record 17.5% below the $100 level it is designed to trade around.
