Unfortunately it doesn't work like that - you have to claim your BCH from whatever wallet/exchange it was in at the time the "snapshot" was taken, i.e. right before SegWit. So you would have to claim it from wherever your BTC was at during that time.
This guide is mainly for those that held funds in Exodus - they had not even announced anything for almost a month regarding BCH, and after some digging yesterday I managed to find a hidden little button allowing us to finally claim what was rightfully ours.
Where were your BTC being held?
Ah gotcha. Mine are on Counterparty...and I don't think they are supporting BCH. Thanks anyway!
They may not support BCH, but they technically should still allow you to claim yours. BCH was issued for every single BTC token in existence, so that means that they received BCH for each BTC token in their accounts, they just aren't giving them out. Which is bullshit.
