Sadly I have not find my way to earn money online. I try to get referrals for the link on my signature but so far I haven't had any luck with it. My referral stats 1 referral and 0.00000000btc commission
I don't know exactly because I have never been addicted. But if you think you should gamble more because you want to recover your losses you need to think that if you keep gambling you will just lose more money just like you have done before that. It is better to be on loss than be on loss even more than you were before.
Thank god I haven't lost any big amounts to gambling. I think it is because I have always gambled responsibly and I haven't got addicted. My primedice account stats show about 0.02btc loss if I remember correctly and after I add wins from their giveaways on top of that I am actually on profit.
You can't really earn with gambling, unless you start your own casino. But you can win a lot and there really isn't maximum, you can win several millions but most likely you will lose of course. But if you get lucky you can become multi millionaire with gambling.
