A class-action complaint accuses the companies behind the stablecoin Tether of “propping and popping the largest bubble in history,” leading to disappearance of $265 billion in cryptocurrency wealth.

Filed in the U.S. District Court for the Southern District of New York on Sunday on behalf of a handful of investors, the complaint accuses the issuer of the stablecoin -- a category of tokens that seek to avoid price fluctuations, often through pegs or reserves -- of manipulating Bitcoin prices.
