For those anyone looking for bounty, this project doesn't need to do that as far as I can tell.
If you check their branch website earn.refereum.com a lot of streamers and gamers are actively promoting it through their channels which is very smart thing to do. They integrate their rewards through Twitch that has millions of subscribers. Their telegram is already 37K+ members and ICO is not even starting yet.
This in my opinion will be the biggest gaming ICO this year and could be one of the most successful project in Gaming industry that utilizes blockchain.
I know right? Untouched quantity of the gaming community has all the numbers just to promote this project to a level in which it can represent just as equal as the bounty campaign all the other project has. Imagine all the gamers around the world, just by their numbers. They could support this project in a sense that they'd be no call for a bounty anymore (in which I don't promote myself, I'd very much like to participate on bounties myself),
the number of gamers around the world could handle the campaign for this project head on.
