Which exchanges are supporting it?
I think at the moment two exchanges are supporting the Bitcoin Interest Fork - one is HitBTC and the other is Okex. I am not % 100 sure, if I am wrong please correct my mistake.
Well, that's a good news because HitBTC is a big and old exchange site that gain trust to all traders in the world. Hoping to see more improvements and good news.
Yes my friends your are right as you have mentioned that HitBTC is supporting this project. And that is great news because has a good reputation.
