loyce, please open your PM for me. I can't write message for you.

I didn't find where I can get SEED phrase in Bitcoin.
For now, I just dumped private key in text... what should I do next?

Hi there!
Before Bitcoin Cash fork was released, I did have about 10 Bitcoins.
Im used it in December 2017, so, technicaly I may pretend to 10 Bitcoin Cash.
But I have no any correct way to get it.
I just have Bitcoin Core with wallet.dat.
I didn't find any way to import original wallet.dat to any Bitcoin Cash wallet.
What should I do?
If you may help to provide step-by-step manual for dummies I'm ready to reward my helper for 10% of my Bitcoin Cash (it's about 1 bt cash)
Thank You!
