I really hope Stox will be huge in World Cup 2018, I think it will be important to have a large campaign to boost the price, and with solid development and decent hype, we will go to da moon.
Also, I think they should stop returning STOX to the wrong predictors during the world cup 2018 campaign.
That risk free promo is going on during beta launch once they will head towards mainnet than they will launch more attractive campaigns to keep involve the people into this platform. But I think attractive campaigns really helpful to boost the growth of this project.
