Yes, it's very difficult, but if you're a gambler, you can really make a killing out of it. I remember one thread in the Gambling discussion board and he says he makes good money out of it. However, he put a his own website give tips and tricks to gamblers and then included his affiliate links. Best of luck!
same here . when i heard affliate marketing or affliate links , the first thing came into my mind is gambling . i dont know why but i was just only involved on gambling recently . i know there other business where we can use our afliate links but maybe gambling is now becoming a thing on present time and most especially in the future here on cryptocurrency . gambling was really addicted because you can profit on it and have fun , no wonder many people are coming back on it
