Where are the real money making on the net?????

Is there anybody that tells the people how to make money on the net that are up for a challenge???

Example:-the people that say that they have a "robot" that make money for them on the stockmarket... need testers for new robot but i must pay to test it for you, GIVE IT FREE SO I CAN TEST IT !

If they make so much money, why bother selling a "robot" to us ?????????

if they really want to help other why must they pay?????
