Hodl? Ha ha.
Seriously, I heard you can't really transfer it until Nov 1 and the value is sort undetermined?
Can I trade mine for some other alt-coins?
Holding of course but not much, bitcoin gold price is really low right now luckly i'm directly sell it before it fall. Actually you still can transfer your coins right now.
I keep my BTC at blockchain.info. I am not sure whether they will give out BTG
Blockchain.info is supporting this bitcoin gold fork, i think you will see your bitcoin gold balance soon.
