No its not wrong while your gambling your playing just to having fun. But it goes wrong when you are losing to much coins. Then you need to get it back and you wont get it back because thats the gamble so stay away of gambling just for your own safety.
I think gambling is something wrong if used for a living. if you just play for fun may not be anything, but do not ever hang up your life with gambling, gambling is something that is not certain where everything depends on the luck that you have, I would have, especially if you're hooked, it can make life already you wake up laboriously, will disintegrate rapidly.
