any sites out and around that are popular?
Im looking to do micro betting on outcomes we can deem are guaranteed fair and not relying on knowing how to verify provably fair.
No I haven't heard or seen any of such site's and it would be absolute madness if a site implements this. How in the world would they make profit? They would end up in looses, plus if one user does not pay, the site would be termed as a scam, so no that's a stupid idea and I would not bet with such sites as this are not trust worthy to me, would recommend you to stay away from such sites or methods as it won't have good results.
to me i personally never seen or heard about such site. although in physical casino we mostly play person to person betting, but in online world i never come across such thing. in my area some time even sitting on a road side we do p2p betting on different issues, but i think it is more risky because most of the time different conflict between the two parties arise which lead to a big clash between the two parties.
