Lots of privacy coins already, Sumo seem to have good price back in the days so it can still succeed. It just need updates and entering into a bigger platforms since its Indodax that has bigger volume. I think people can see that already but shilling the coin every minute in the forum might not help its reputation, instead post an updates of what is going on in the project.
Come on mate, I wrote one post and started one topic to discuss SUMO - i did not do so in many many months. I would not count that as "shilling every minute" I ususally post the updates on SUMOs ANN, people can check there and on the other social media the project has. Anyway, since we are on the topic here are the two latest wallet updates: a webwallet and an android one:
