I don't think you can claim them yet, and I don't think they can even be mined yet. It will probably work just like with the bgold fork and we need to wait for their official announcement. There are plenty of wallets listed on their site, but I don't really know them, so I'm not going to try those. Even if you were able to claim them already, you wouldn't be able to do anything with them. The only thing that is being traded now are their futures, so I guess that actually means that there are no coins available at the moment.
I'm not sure about this one to be honest. If you go to their site, you actually see a picture that compares them to BTC, bgold, bcash and B2X. I mean, they could at least change that, and removed the B2X since the fork was canceled. I know this might be a little thing, but for me it shows some lack of dedication to keep the information in their site updated.
