Nowadays people make huge money playing at HappyMiner. Here we are not talking about it. We're talking how to get $10 on the sly while they are making thousands of bucks.
how to make money playing on Happyminer" The people made this money by following the instructions from here

In a nutshell they buy Happyminer's accounts for $10 and then sell for $12, so $2 profit on every account.

Because of big money making, they generate Happyminers coupons. Every coupon could be used to get a Happyminer's account. Then the account can be sold for $10 on Virtaex. $10 is nothing for them, because they are rich, but we can use the coupons to get our penny! Perfect! I love it! I found a coupon generation algorithm, and can generate many coupons! Wow! But they banned me sometime for using it :(
And I decided to generate and give the $10 coupon for free, BUT you must tell about this site on some forums. This is the condition. You tell about this site on 5 forums and get $10 coupon! A good deal for everyone. But it's a time-limited offer. May be the offer will not be continued after 1 month, if it's not efficient. And also, everyone who got $10 coupon from us, must send a short testimonial to us with a screenshot like above. It's the second condition.
