Grupo Circuito Goiano

Last week I was watching the Flamengo vs Palmeiras match with some buddies, and we started talking about putting some money on the next games. I've never really done online betting before because I always hear horror stories about sites stealing your data or refusing to pay out. Anyway, I was looking through a local sports blog today and stumbled upon a link pointing to the 1win site oficial. I'm super hesitant to click or sign up without doing some homework first. Has anyone here actually used this specific platform? Are they legit for Brazilian users, and is it easy to deposit money? I really need some honest advice before I risk my hard-earned cash.
