We'd like to clear up a few misconceptions for those in doubt about what, exactly, the Bitcoing Gold replay protection (or lack thereof) really means.
So, while replay protection is a must, all the FUD and noise being spread on chat rooms and social media are simply misinformation, spread either by ill informed users or trolls.
The important thing to know is: There is no BTG trading going on anywhere, because it is impossible without miners. And miners cannot work at this time, yet, because BTG transactions could potentially interfere with BTC.
BTW: There is currently a 250 BTG bounty for anyone who develops proper replay protection on Bitcoin Gold. (One would expect their core dev team to be able to achieve this without outsourcing.)
