SV lost the battle with ABC. Fortunately for BCH holders, ABC has gone up so much recently that they haven’t lost out with fork. Having said that, SV has gone from $50 to nearly $200 in May. Hopefully, it will eventually be possible to upload and sell them on Bitstamp.
All my pre-fork BCH were on a Ledger Nano. I looked at the process for recovering SV recently and it was so convoluted that I haven’t yet bothered.
