I don't know about marketing it more. I'd say Giga-Watt should keep their focus on the construction of pods. They already have more mining equipment on hand than they currently have space available to put it into service, and that doesn't seem to be changing even as they bring more pods online. They also have some of the WTT token holders upset enough about the delays to bring lawsuits against them, and other WTT token holders unhappy about the delays, but willing to wait.

Big exchanges don't always lead to more volume, but it can. There is only big volume where there are significant numbers of parties on both sides of the trade, regardless of the exchange. If there is sufficient investor demand, they will figure out how to use the existing exchanges.
