I just separated my gambling wallet from my rest of the funds and that is biggest achievement I see for me. I helped me a lot to control loss though I am not in any at the moment. There is no strategy to win continuously in gambling but having limited your fund is good strategy to play with some planing like when to stop and how much to go with in case.
I do the same thing! i have a separate gambling wallet which i fund once in a year with .5 btc and i try to gamble with allocated funds for whole year. also i don't deposit not more than .05 btc at once.
