As far as I can understand, the problem with listing the current ROC1 token is that it gives dividends and therefore deemed to be "security" and no exchange want to even touch security token.
The good news is that, the ROC2 token is utility only and once it replaces ROC1 at the end of ICO, the team should have no problem find it an exchange to list it.
It has also been mentioned that Rasputin plan to implement a native "one-click" purchase of ROC2 with credit card on their site. ROC2 holders will simply need to submit their token with a price they'd like to sell to Rasputin's site, with the proceed send back to them when someone purchases.
