Would that make a difference to you, the amount of accounts? I don't use online accounts I use cash down the bookies or at the races, but if there was five bookies down the high street I wouldn't go into all of them for a bet. I'm not having a go at you, just interested why you regard having...
Would someone with an addictive personality really be that interested in their slow accumulation method, I probably wouldn't be and I enjoy gambling. I don't have the patience for all that frigging around.
Most of the bookies will cover themselves by laying off the bets with other course bookies and betdaq/betfair. Outsiders winning usually means bookies winning.
