As far as I know nobody has tokens yet. HitBTC has future contracts, they trade not the tokens themselves, but the rights to buy the tokens in the future.

In finance, a futures contract (more colloquially, futures) is a standardized forward contract, a legal agreement to buy or sell something at a predetermined price at a specified time in the future.

I wonder how they are going to enforce the transfer of the actual tokens though. Maybe the futures are trading lower because of that uncertainty.
