That is a very good question. To be honest, I am not 100% sure but theoretically you should be able to do that and still recieve your BTG. Practically it might be a who different ball game. I think its very high risk, so I really would not recommend what you are trying to do. I hope someone with a technical no how will be able to give us a proper answer.
Believe me no "technical" someone will be able to give you a proper answer.
Bitcoin gold themselves don't even have a defined date to when the blockchain will go live. They just stated that it will be after Nov 1. But when ? -----no answer-----
Anyway it's a blatant scam way worse than even Bitcoin Cash. They're pre-mining a lot of coins. The only reason people are still giving it heads is that it's coming for free. But if this weren't the case, you would see every single person on here screaming (pre-ming )(preming)(scaaam)(scaaam).
Back to the OP. Don't move them because nothing is clear. Just wait after the block is reached and someone might come out and state something.
