Only had it happen to me once, it was when I first started gambling.. only 18... and man was I good.. only made one d/p took a bunch of cake over a year... and i didn't know half the stuff i do now.
Better to be lucky than good.. lookin back on it, i have no idea how I did so well
They ended up cutting my limits to $25... when they sold the site, they removed my limits.. and my luck
