Hey there, I'm so sorry for the delay in our response here! Yes, we would recommend not doing anything until proper replay protection has been put in place.
In regards to adding B-SV, we are keeping a close eye on B-SV and if it continues to be a top performer and meets our listing criteria, we most certainly would not ignore the asset for inclusion.
We would like above all, first, to provide our customers with a safe solution to split/claim their coins without needing to expose their private keys to a third party service.
If you'd like to see B-SV in Exodus, I'd be more than happy to take note of your request! =)
