All you need to know about Sportsbet limits: 3 mBtc max bet on Leeds - Fulham https://youtu.be/hVdQdANCLLg
Big players are not welcome

I saw an ad about a partnership with Arsenal and decided to play with you. Made  deposit 100 mBtc (0.1 BTC) and wanted to bet 20 mBtc (about 180 EUR only) but could not because of an error "Selection liability exceeds your limit. Your stake has been updated" but my stake size has not been updated! Screenshot:
As a result  I can't  place 20 mBtc, I can't see my max bet size and my sum at betslip is not updated. WTF? What about  Max bet is up to 100 BTC on match! at your first message? It's not true.
This was my first and last bet at Sportsbet. Awful sportsbook with very low limits
