Intresting project for sure, devs do not pusrit listing on exchange rather they are improving the basis of project. Solving capthca is a decent and fair way to distrubue coins amongst community the harder you woprk the more you have. Right now the one coin costs aroun d 0.04 $ so this pays out much more than captcha solivng websites. However I thibk the project need more advertising or it will die eventually.
