Noticed many Indians posting here on IPL betting.
If you don't mind, how are you getting on the action? Some folks I know were using Betfair but it stopped accepting India customers recently. Are you using a Betfair clone in India? (would prefer Betfair over a book honestly)
Talking legally you can use the fantasy sports which I heard is very popular among cricket fans and they earn money doing that. Now coming to illegal gambling you can easily make an account on any sprotsbook in crypto and bet as much as you want, but do that at your own risk because this is something I cannot approve personally but lot's of guys doing it.
Sports betting as far as I know is not allowed in India and guys gambling on these crypto sprtsbook are enjoying their time but they might landing trouble if these platforms ask identity proof and later you have to admit that you made an illegal accounts and bets.
