Well, it requires just one investment of about $15 ( in BTC ) and that's it for most people ( that's  why "Make $500 with Bitcoin on Autopilot )

However if you are willing to dedicate some time and drop the "autopilot" you can generate much more than $500, but since people are lazy I just guarantee the $500.

Also, as a newbie I'm not allowed to send PMs to some users, so members requesting vouch copies should allow newbies to PM them or give an e-mail so i can send the copies. Thanks.
