10% is a good threshold, to earn a monthly profit we have to apply a small percentage every day and not be tempted by massive instant income. In this case, I left the game freely and used to switch directly to another business model so I was not fixated on the percentage in a gambling business.
We can leave the game anytime we want but for someone like me that is addicted then that kind of thing is hard to do. Sometimes if we cant leave the game, we can control the amount that we are playing that is what I am doing so that I keep on using small amount. This way makes me cant hurt myself by gambling amount that I cant afford
