From Twitter:

"The team will be revealed in time. Security is our top priority for the exchange. Our directors are custodians of customer funds and it's important to disclose their identities to the public responsibly without putting client funds or their personal safety at risk."

This makes sense. Not sure why they didn't say so in this topic, or maybe they did somewhere and I missed it. Maybe they omitted it on purpose. The mystery did after all generate a lot of activity, 101K views and 100 pages of conversation...

Team from Apple --> mystery is exactly what Apple uses for marketing because it gets people talking -- secrecy, no product announcements, rumors, leaks, etc. until the final product is revealed and puts all speculation to rest.
