i prefer on sports that I know and follow. I will not put up without having knowledge of the team because it usually makes losing money
Yes it is the best thing to do, Just follow the sporst that you know so that you can't blame your mistake to others. Because if you'll bet on the sports that you don't know and you are just follower of a tipster thread. If you lose, then you'll blame the analysis and choice with that thread but its your choice, better to gamble what you know.
to me although i mostly play gambling on such sports where i have good experience for example in foot ball and cricket i have good experience to gamble Because i know all the players and cricket team on international level.i know all the good and weak point of all the cricket and football players therefore i am very confident while playing gambling on such games but still some time i also play gambling on such game where i do not have any experience.
