So I don't understand how you got IOTA mixed in with the ICO thing. They aren't allowing trading of "ERC-20 TOKENS" after Aug 16th by US customers since they are classified as securities now by the US govt. IOTA has nothing to do with this and is still available to be traded for the next 3 months with no problems on Bitfinex. They are allowing a grace period to prevent a massive sell off on their exchanges.
