I do keep a record of all bets and the last 6 months I am up overall across my 3 accounts. I do find the bonus bets a big help, getting free bets is something we never had until recently smith TAB, would have loved it 20 yrs ago.
Somebody did tell me once which I do every week, withdraw your money out on a Sunday evening, nobody will offer you many match deposit/ bonus offers if you have money in account. Sure enough, it works. So there goes your theory about me losing all my money, that’s not me.
