Hello adamhiggins82,
The trades going on at Yobit, are from the forked B2X balances that the people had of BTC at the time of the fork.
No one can get a DEPOSIT address yet, until Yobit makes it available.
Your mining B2X coins must be kept in your own wallet, or pool wallet, until the exchanges open deposits.
So if you had no BTC in Yobit at the time of the fork, you can't join in the trading just yet.

Regards,
Just understanding this, and if it's a scam. So you're saying if you had an offline SW wallet, no way to use your keys with their new wallet to trade coins? Doesn't that defeat the whole purpose of this thing?
Also of course there are hacking concerns, replays, etc... so not sure putting any private keys into this thing is safe.
