They make super secret to create a buzz but I think it works like this.
1. You buy a code from some guy for BTC.
2. You send an email to a bot that invalidates that code and sends you back two fresh ones. Thus doubling what you have.
3. You sell the new codes and get BTC.
4. Profit!
I can't believe some people can fall for that.
finally someonewho can give me a little insight on this. total ponzi style scam then. Thanks! if anyone wants my code they can have it for free lol
