Claiming my BTG from my BTC private key I have a BTC private key, how do I get my BTG? I have tried a few methods and tutorials but none seem to be working.
And beside that, is there any working BTG explorer? All the ones I found seem to be buggy (including btgexp.com) and wont recognize my address.

EDIT: yes I had BTC on this address at the time of the split

EDIT 2: found a working explorer with https://bitinfocharts.com/bitcoin%20gold

EDIT 3: yes I have transferred all my BTC to another address, and I just want to get rid of my BTG now
AFAIK there's one good wallet other than the reference client that can import the private key and make a transaction.

That's Coinomi, it can import the private key and does support BTG.

(When I wanted to dump and sell my BTG, Coinomi was great, although I needed to use the Android emulator Genymotion [because I don't have an android device])
