So basically we will get it but won't be able to trade it, right?
You will get it although I would not recommend trusting any exchange I would still rather keep my own private key and then move to a exchange after to sell or trade once trading is activated.
With BitCash those on the exchange benefited a lot more yes but that was due to the really long block times BitGold shouldn't have these issues due to the mining hardware used I will be mining from day 1 as soon as possible with whatever pools are available but will switch to suprnova if/when its available I just mined a bit of Zcash there yesterday to sort my configs and now just need to change the pool address if/when available and there seems to be huge mining support elsewhere unlike ButCash had
