I have a couple of suggestions regarding crypto betting sites:
- if you are not a citizen from
Belarus, Cuba, Iran, Iraq, Côte d'Ivoire, Liberia, North Korea, Sudan, Syria, the United Kingdom, the United States or Zimbabwe.
you can bet using Augur and this system.
- Another option could be Wagerr (This is a crypto coin based on waves platform).
Other crypto gambling website "promoted on line as decentralized sports betting" are: dexsport.io - betdex.com or betswap.gg
I have never used by myself make your own research...
