scams or not

[Appenomot]

there are some sites on line that advertise a system that consistantly generates 15-20% profit a day. Do they exist? Is it worth having a look at what they have to say at least or should you just stay away and work on your own systems?
I'm sure many of you like me have paid good money for information that promised the world but did'nt deliver. Do any of you still look at everything or do you stick to your guidelines?

Let me know.

Ask for a free trial and if they wont give one then dont believe them. If they are that good then they will have the confidence to give a free trial knowing that it delivers on its promise.

I think they are mostly scams ... in the if its hard to believe its not true mold ... but I wouldnt give a free trial if I was them. I have let two traders have little bits of software I custom built for them on the understanding that they would pay up when the software worked. LOL. Guess what - time to rachet up the cynicism one level.

I have an easy answer for this by means of a question. If you had a system that generated 20-30% a day in profits would you need any other source of income such as a website to sell things like "systems?" Obviously the answer is NO. Besides the point, why would any intelligent individual let the world know about their system that makes them 20-30% each month?
