There are many threads of gambling websites in this sections, so in the end is up to you to do some research, but I would suggest you to take a look at https://www.Crypto.Games.

Why?

- Provably fair
- Quick support
- Live chat with RainBot
- Low house edge on dice (0.8%)
- 8 Games, incl. 0% house edge lottery
- 11 coins
- Voucher giveaways, challenges, etc.


But as I said, it's up to you to do some research yourself first.
