OK so firstly, I was not fussed about BCH, but I thought it better to split them on my Nano Ledger S away from my BTC.
Looks like I messed up.
So my ledger was up to date, as was the Chrome extension.
I booted into the ledger and there was my 2BTC that I have been adding to over time.
I swapped to Bitcoin Cash then hit the split button which created the new BCH wallet.
Now what I was supposed to do, was to go back to the Bitcoin Cash Main, and then split from there.
But instead I went to my BTC wallet chose max and sent to the newly created BCH wallet.
I realised what I had one, and straight away the BTC balance was Zero.
I logged into the BCH wallet which was also Zero
Logging into Bitcoin Cash Main, there is my balance but only as BCH I.E 2 BCH
Now I am panicking that I have lost my 2 hard earned BTC's.
My BTC and Bitcoin Cash main wallet have the same receive address.
Can anyone help me retrieve my BTC or are they gone for good
