Well I choose Bitsler and Bitdouble.io. Bitsler because I love how the events happening in that site where you can win BTC without loosing high amount of capital. Plus, the community is very close to each other the same with the developer. You can speak and have a joke time with them as a regular person. I'd love how they solve the problems as fast as they can and im very excited with their future updates which will make their site more popular and maybe rank first in the future months. Next is bitdouble. I love their updates and I hope in the next month they will be well knowned in terms of  gambling. Their advertisment is their great asset towards the spreading of their site and their updates were great also. Looking forward to see these two sites in the top 3 soon.
