Buddy, just go the gambling section of this forum and try any gambling site where its owner is active. So if you have any problems, you can easily address there. In all gambling sites you can start with small amount. But the problem is if your deposit is very low and if you want to withdraw after gaining some profit, you will have to spend your profit as transaction fees for withdrawal. So finally you wont gain anything. If you want, you can try this site https://www.crypto-games.net. This site is really good and it accepts ten types of cryptocurrencies.
