No one is your advisor in this matter. After all, everyone starts from their own preferences. Someone may be a football guru, while someone understands and is only interested in cricket. So, first of all, ask yourself this question: what kind of sport do you like? Choose that one. But I can help with bookmakers. There is a website https://betraja.in/
which provides reviews of the best bookmakers in India. Here and choose through whom you will place your bets. And don't be upset if something doesn't work out. All comes with experience.
