Are you referring to a token from a project that is really into mining? Yeah, I think we have those operating and being traded in the market these days though am not particularly a fond of this type of token because in most cases the growth is quite limited and can be subject to the ups and downs of the mining business. Though I supported some of them when they got into bounty promotional campaigns or some airdrops but so far nothing really gained some value...but I am waiting for Spider Pool just in case they can be releasing the tokens they promised to us.
