Betting on sports is getting popular with the rise of crypto because of decentralization and easy transaction ,
At all i clearly against of any betting because of risk of loose or win but if you are expert of sports then its only your decision , i advice you to invest in real business because i see many people that says we are expert and after 100x their money they loose all that money one day , and thats a reality
So invest in only stable currencies buy some dollars or buy some forex currencies because they get you profit slowly but not go to zero any moment like in betting .
