While Bitcoin Gold is very little publicly available technical information, which is rather strange considering that prior to the appointed date remained not so much time. Bitcoin Gold will have the same address format as bitcoin and Bitcoin to Cash. This has created problems — there are reports that people are sending huge sums to the wrong address.
Finally, we should discuss how to come about branching.
Because Bitcoin Gold has virtually no chance to replace bitcoin, each bitcoin owner Bitcoin will also receive Gold when you start. Personally, I believe that they have no chances for future, and not that much support
Underlined part of course. But wait there is more: No replay protection.
When you try to redeem your BTG you are factually exposing your original bitcoins to get moved, too. Only defence against that would be moving BTC first, then importing the private keys into the BTG wallet and moving those airdropped coins on an exchange site for sale.
Never ever using the old BTC adresses again. Sucks.
Still investigating where to act, today just found futures traded on Hitbtc or Bitfinex.
