I deposited $500 a few week back. Up to $5K now, not through any promos, just mug bets (that I had countered elsewhere) that mainly unluckily won on Sportsbet. All my bets are getting manually reviewed before being accepted, but none have been declined. Hopefully this will stop once they hopefully work out I’m a mug who just got lucky with some bets early on.
It’s more than just the amount you’re up though. It really depends on your bet size, odds and how many bets you’ve had. If you are betting $500 and only had a small number of bets, then it wouldn’t be out of the norm to be $1500 up at some stages. If you’re betting $5 stakes on 2-1 bets and you’re $1500 up, well that’s probably going to raise more eyebrows.
