of course "risk free" is to see in limited way.
External risks are always possible.
But these risks are as well possible with risky systems.
I have programmed 2 systems...
one I call it risk free with profit after 100 days.
the other one is risky because we have the risk to see the ROI only after 100 years or never.
of course the aside risks are bigger with the second one because the plan lasts over 100 days.
But aside risks are as well possible with sign campaigns...
But neither system is "risk free" When you claim the first system is risk free you are being dishonest. The first time it was possible you simply didn't know any better, but by this point it's clear that you do know what risk free means, but you still choose to describe your system as risk free. That's dishonest.
