All gambling game is sure have a risk thats why the payout is good, if there is no risk I dont think you can really earn money from gambling. Btw what I do know is the most profitable gambling is sports betting because sportbook already give you their odds, it is your time to gather more information to boost your winning chance on sport betting plus there are tipster nowadays that really help you to get more information if you dont have time to search it
Yup sport betting has a chance that you can win it by knowing who's team or player that has a good performance then that will be your bet but their are a slight chnace that you will lose because you will never know who will really win until the very end of the game right?
