I merely suggest that users try it out with a small amount.  If I run away with someone's $3, they can laugh at me because the website costs considerably more than that.  If the system actually pays out, then users can have a fun game to play with (just like back when ChainProfit was around).  As a user of ChainProfit for a long time, I made a considerable amount of money with that system, and was disappointed to see it go.
