UPDATE: Arbitrage opportunity - see screenshot below!!
Claiming BTG with your Ledger has caused a bit of confusion, so hopefully this helps you claim your Bitcoin Gold!
Quick tip: make sure your firmware is up to date and you may need to uninstall/re-install to get it to work. Also the little "BTG split tool" is easy to miss.
Watch to the end to learn what to do with it once you've claimed it. If you decide to sell I've got a quick tip for you to get the best price.
Good luck!
