everything has limits and none of the bitcoin sport getting sites can handle mayapans bets(ranging from 20M-30M$). I dont think any site in the world will allow these bets.
One of the real world bookies (or maybe Meyyappan himself) should start a site.

Big betting happens with a chain of bookies and not a single bookir. Mayappan himself was a bookie, hr can start a site like that but that would only increase his problems
