Is there any Legit sport betting challenge currently where they give you BTC if you win most tips or achieve highest win-ratio. Gonna put some ink onto my body and I need money for a tattoo so I will try to win that challenge. Let me know if there is one running right now

These are monthly competitions so you still have a week or so to catch up in the leaderboards. Good luck.
