They might have just hired someone, outsourced it. Lots of projects do that nowadays.

This is what i am afraid about. Name one good exchange where the main team doesn't have a background in coding.
Outsourced help isn't enough because exchanges aren't finished products that you sell, but they need a constant maintenance because of hackers and growth.
Yeah. You're right. The most probable thing to happen is the team would only permanently hire a coder after their IEO/ICO. Currently, they probably don't want to spend extra funds for it especially when the exchange itself isn't even running yet. Although, this might never even happen if their IEO/ICO wouldn't have great results.
