I can suppose that other famous players are already busy. Or among other players, Suarez is famous for his biting. I dont think that Duelbits are focusing on Brazil only (not because Suarez plays in Brazilian club definitely, because Duelbits are official sponsors of Premier Ligue club), but they are focus on South America in general. Suarez play for Brazil club, he is from Uruguay itself, and Argentina with new president (who cheers for Bitcoin) is near.
