r/cryptocurrency has been cracking down on "shilling" posts recently. There were tons of posts each day pushing a coin so I guess the moderators got tired of it and added new rules. Right now the best way to get a post about your coin in top of the day would be through a reference on NBC money or an ad in the Wall Street journal. My suggestion would be to pay for an ad in a notable location, maybe something to do with the Superbowl and then have someone post a link to r/cryptocurrency.
