Seems to me this is all wrong.  The theory that they are scamming is based on this email address registered to NOT BITCOIN GOLD's DOMAIN!!!!  The real link is this bitcoingold.org not bitcoingpu.org so the real look up is here not the one originally posted.  https://www.whois.com/whois/bitcoingold.org
I can't say whether or not bitcoin gold is a scam.  I can say their CEO is a well known public figure though.  My guess is the OP stumbled upon the wrong website (probably setup by a scammer trying to phish).
