We're talking about two different things here. The BitGold airdrop is slated to happen in late October. That should be a non-event..... I'd be very surprised if that fork were offered on major Bitcoin exchanges. Maybe Poloniex, Bittrex, Cryptopia and other altcoin exchanges, though.
The Segwit2x fork is different, because it's backed by major services, exchanges and miners. I'm not sure what's going to happen. A split seems likely if the BTC1/NYA crowd moves forward with the fork, which would be bad for the price.
What is BitGold ?
Is BitGold = Bitcoin gold ?
How can get BitGold? it's like BCC?
