i afraid that i am not the first person shooting this question:
is there BTG (bitcoin gold) support at near future?
This has already been answered, everyone who had BTC balance on SD at the time of BTG snapshot will be credited with BTG. if you by support mean, adding BTG on SD(gambling/investing) then it probably won't be supported(you can ask thesourc3 for a definite answer).
