I would avoid this advice. If you've never purchased gold and then you log into a VPN, take 40M for nothing, and then never use that IP again; it will look a whole lot more sketchy.
You're usually fine buying gold, just use common sense and don't go bragging about it and as mentioned before don't make hundreds of trades. If you're planning to get 40M and get out, then you're awfully safe in my books.
