Gosh, I didnt. Thanks for pointing that out. I actually followed a set of instructions from elsewhere, and only referenced point 6 here as it had to do with the xprv issue that you kindly clarified. I got the addresses from coinb.in and finally got my complete command configured. I tested it in offline mode as I don't have the chain synced yet and got the error "Method not found (code -32601)"....
I went online repeated all the steps and finally got "Complete" :  true    

I avoided having to sync the entire blockchain by broadcasting the transaction hash from https://btgexplorer.com/tx/send and I've got my BTG now!  

Thanks OP and HCP.
