The creators of Tether, a stablecoin with a market value of $83 billion, have profited greatly from their creation. Despite the overall decline in cryptocurrency value, Tether has remained successful due to its low-risk profit-making model. Tether's top executives could become billionaires if the company is sold for an estimated $9 billion, but regulations and demands for money market returns may pose challenges in the future. Forbes reports that stablecoins are now yielding between 4-5%, and at least one US company plans to create a regulated stablecoin with money-market-like returns this year.
