Buck Labs has launched the BUCK token, a yield-generating "savings coin" initially priced at $1, with an target annualized return of approximately 7%. The token is backed by shares of MicroStrategy (MSTR), generating income every minute. However, it is not a pegged stablecoin, so its price may fluctuate. The yield funds come from the preferred shares of MicroStrategy STRC held by the foundation. The token employs a governance mechanism and is initially available to users outside the United States.
