I heard it that Bitfinex has established a moratorium on cashing in tether tokens held by its customers. These tokens were created by Bitfinex in 2015 to allow customers to exchange an asset that's pegged to the dollar at a one-to-one ratio, allowing them to avoid costly wire transfers that must be processed through the banking system.
But the withdrawal freeze has put pressure on the tether market; for only the second time since they were introduced, investors are selling these tokens at a discount.
