<p>I just realized that when I sent BTC from Mycelium, it split the value from a source address into two target addresses, but the BCH of course stayed at the original address. I'm concerned that I can't verify that the private keys Mycelium tracks cover the spent address. If I export my Mycelium keys to a wallet that supports BCH, will it still be able to access the BCH that was at the spent address?
The spent address (public key) is 1FfbdfD6bfwy1HXLTznGnUVsBTxZGMXDod and I can see Mycelium knows about the unspent output address that it still has, but I can't see what addresses it's private keys cover.</p>
