Always withdraw winnings...keep your bank at a set amount..and dont be tempted to add to the bank during a rough trot,,,i find that when my bank starts dwindling i'm more selective and succesfully get back to the original amount..
After each 1/4 i then add a percentage (25%) of winnings to the bank,,
My goal is to have a bank of $100,000 using this method by the end of the next finiancial year..,,i'll then try being a fulltimer ..
hopefully with the extra time i'll have i'll look into sports betting more seriously as i can see mainly by this forum that it can be profitable..

this system has worked for me for the last 19 months or so ,,,i've never needed to top up my bank ..even after losing 30% during a hard time..

i also spend most of the winnings i've withdrawn..to alleviate temptation..
pay off the house , any loans or credit cards ..or put it aside for a trip to the World Cup cricket tournament in the West Indies in the near future,,
