when is the BTG blockchain supposed to become live (if it ever does and isn't a scam)

?
I had the impression before that the scheduled date was Nov 1st because that was when BitFlyer had announced they would release tokens ("If the security of both chains was ensured")
but looking at the official blog
https://bitcoingold.org/bitcoin-gold-daily-dev-update-28-10-2017/it looks like its only testnet which will be released on nov1st

?
WTF

?
Why did BitFinex release those BTG tokens well before the chain is live and make anyone holding a short position short those tokens

this is really a SCAM
