Thank you for posting this thread - I'm also a victim and feeling pretty stupid right now. Bitcoin Gold had
http://mybtgwallet.com/ listed on their official site as you say, and I too fell for it. I lost 0.08 BTC, and after today's run up I was going to sell it off. $800 CAD down the drain.
Is there anything that can be done to recover funds (I am a noob, but I keep hearing about replay protection - is there any protection from this)?
