If you have the "computer whiz" traits, and if you want to hack someone's computer, its not dependant on how much logical skill you have, but what type of computer you use.

If you use an old computer, from 9 p.m to 7 a.m, you can only make around 300 dollars.

But if you use a laptop, from 9 p.m to 7 a.m, you can make money, at least 1000 dollars, and sometimes 3000 dollars.
