Quote from Visaria:
1. Yes, more than i care to admit. I have made excellent money from it in the past, however that's because the big arbs were in the past and bookies would let you do big bets. The profit margin for doing arbs these days is v low imo, not worth the time or effort.
2. Yes, however I am based in the UK, whereas I believe you are based in the US where I believe sports betting over the web is illegal?
3. They will probably limit the amount you can have on a wager first. Then they may close your acct down.
4. No.
add: actually, you will find it near impossible to open an act with any online bookie, they do not take US customers. If you manage to open one, they will void your winnings and probably confiscate your money when they realise you are from the US.
