Yes i just played for 4 hours straight and i made some good profit in the end if you are going to think and always revise your strategies make sure that you are not greedy when you are loosing too much gambling is need patience and don't it to be rush gambling can really be a profitable in a long term of playing.
How about giving some proof about it? If you are only making few dollars then that is not worth the time and risk to play. In the end we are going to lose in the long term so dont even think of trying this again. You might be winning today but there is no guarantee how things will turn out the next time you play for this long
He doesn't need proof, people get lucky all the time but if he keeps going in the long term he has no chance to make a profit.
