Why our STD to USD rate has no second version
Most websites publishing STD to USD exchange rates are run by money-transfer services. They display the mid-market rate to attract visitors, then quote a different "customer rate" once you start a transaction — typically a 0.4–4% markup, sometimes more. Currency.Wiki doesn't sell transfers, so the rate above (1 STD = 0.0000 USD) is the only rate we have to give you. There is no second rate applied later. Same number, different incentive.
