what is the maximum that one can earn online????????????

There no limits to how much you can per day but you need knowing where to start by doing research and where to invest. There also free programs but you earn so little!

I just started around 2-3 month ago in this line of activities.. on my first month I just earn cent because I don't know what site I should get involve.. After searching many forum and searching many sites, I'm now earning around $100 per month with just 2-4 hrs a day in facing the internet because I'm still a student.. I just based it on my experience..

a million dollars, only if you have enough money and the proper mindset.

depends on your skills actually. and I think there's no LIMIT earning on the web. the problem would be your capabilities.
