Bitcoin Gold is the latest Bitcoin fork with the split occurring on Bitcoin block 491407. The coin is seen by the developers as a response to the ASIC driven monopoly of the main Bitcoin chain. As with the previous Bitcoin fork for Bitcoin Cash (BCH), as long as you are holding Bitcoin in your own software wallet when the split occurs you will automatically receive an equal amount in Bitcoin Gold (BTG).
Users with Bitcoin in hardware wallets or who have them on exchanges wishing to also receive BTG would need to check with their wallet manufacturer or exchange to find out if they plan to support Bitcoin Gold.
Bitcoin Hardware Wallets
In a recent blog post Trezor announced that although their devices support Bitcoin Gold, users won’t be able to do anything other than holding it. Users can choose to export their BTG, however, that is not a procedure they recommend. The coins will therefore not be available in the Trezor wallet.
Trezor’s main issue with BTG is that the code for it currently offers no replay protection, meaning that due to the nature of the chain split there is a potential to lose or transmit your Bitcoins rather than just your Bitcoin Gold. Their advice therefore would be to simply hold the BTG until replay protection is implemented by the BTG team.
The Trezor team states:
"Yes, TREZOR (the device) supports Bitcoin Gold. As previously mentioned, at the moment of the fork, if you have bitcoins on your TREZOR, you will also receive bitcoin gold on your TREZOR (both new and legacy accounts are supported in bitcoin gold). If you simply wish to hold BTC and BTG, there is no further action required from you."
Keepkey has announced that they too will be following the same measures as TREZOR by allowing the users of their hardware wallet to receive BTG but not immediately transact it. They advise users that if they require the immediate ability to move their BTG coins then they should, “relocate their Bitcoin prior to the October 25, 2017 deadline into a wallet that has confirmed support is already in place for this new asset.”
