I have unclaimed BCHA (now eCash) sitting in my Android mobile Bitpay wallet, but I can't find the private keys of the address, how to do that ?
Whenever I try it takes to a private key encoding my wallet, not a specific address.
Did you contact the support before post here ? There should be a support on how to extract the private keys.
I just did that and they gave me a way to get the private keys, not directly from bitpay wallet but through electron cash, which worked and now I am safely transferring my BCH to a totally new wallet and my ecash to an exchange to cash in a couple thousand dollars, christmas was early this year.
Glad to hear that you succeeded solving your problem.
I wish also to know more details about how you got them exactly. I have an old bitpay wallet too but i don't know if i own BCH from the fork as BCH wasn't yet supported by BitPay apps..
