I would recommend using the HITBTC trading platform to buy STX. In comparison with GAte.io, HitBTC has more liquidity. I also would like to ask the developers if they manage to execute their road map and when it will be possible to put real STXs and win the predictions of STX. By the way, the price of the token is now a record low for all time.
Maybe after the finish of ongoing promos they will announce their next plan to implement this system to win real STXs instead of risk free contest. I think than it will get succeed to catch of attention of more users like we can see a large number of people are involved to make predictions for soccer event. This is great success for this project and their marketing strategy working nice.
