So i decided not to gamble with them can any one tell me what are the other options which i can do with my earnings.
gambling is not for earning its just for fun and never put your money in gambling. if you want them play for fun with free coins.
You could gather all your earning and make a good purchase of digital goods like a game or upgrade your pc to a gaming beast or something you could gift your close one something in surprise
Its better to spend them instead of loosing in gambling, as you will surely loose all your earnings if you put them in gambling, the best thing to do is to hold them for future.
