Definitely sounds sketchy, though it still sounds more legitimate than MobileCoin. At the very least Akoin has a timeline of when all the coins will be released, something MobileCoin has so far refused to give.
At least with MobileCoin you kinda know what you are getting - it's to let you send anonymous payments over Signal, funds raised go to Signal and or it's founders - if you don't like that don't use it. This sounds more like a con where they appear to be charitable but the money all disappears somehow.
