$5 * 3 models per day=$15 a day

Assume the experiment runs ~250 trading days in a year, consider the worst case they lose all their invested money=$3750.

A little more than $5 :)

Good point.

That said, many hobbies cost more that $3750 per year, and that $3750 is a worst-case scenario. He might even make a profit, and hone skills that might make him a fortune.
