Michael Saylor, founder of MicroStrategy, has identified "digital credit" as the next major opportunity for the cryptocurrency industry. Speaking at the New York Digital Assets Summit on March 26, Saylor introduced MicroStrategy's preferred stock product, STRC, as a low-volatility, high-yield fixed-income instrument. STRC offers an annualized yield of 11.5% with a volatility of approximately 2%, a Sharpe ratio near 4, and a notional value of $5 billion, achieving institutional trading scale with average daily liquidity of $224 million. Saylor emphasized that STRC's volatility is lower than that of traditional bonds, the S&P 500, gold, Microsoft, Google, and Bitcoin. However, some critics have expressed concerns about the sustainability of STRC, suggesting that its returns are contingent on Bitcoin's price appreciation and MicroStrategy's ability to maintain favorable financing conditions, which could be challenged during market downturns.
