so my guess is 1LfqTBBFP the BTC address on topic here.
I'm not quite familiar with bitpay but I read that bitpay wallet user owns the key
if you have its privkey meaning you are in control of the address
you can simply use the same privkey and import into your BCH wallet
you need to ask bitpay how to extract a privkey of your specific address
Your quess is right, So i need Bitpay to reply badly.. When they do i will asked them what you said.
I'll keep you all updated on what they sais and if they can and will help me.
Thanks a lot everybody
