It has been shared above already, I guess it's better if it's a crypto gambling site as we are in the crypto world and that would help crypto casinos to grow.
But I guess KBO is not available in all sites that include cryptocurrency payments I don't know the reasons why but it is available with 10bet
They are available, if you read above your post.
I should have edited my post it should be mostly cryptocurrency site KBO is not available and when I have looked at Onehash pretty sure it is available
but Cloudbet and Sportsbet was not really available if you had look on the provided link
