That’s actually an interesting point. You affecting the system will change the situation and therefore might have effects on the outcome. Might be minor like the value of bitcoin only varying by a small amount but it could also somehow cause Bitcoin to crash and never recover.
Same with the idea of investing all your money into a company like Apple. This could affect the development and decision process of the company and therefore cause them to fail.
So there is no guarantee for your actions to turn out successful.
So a virtual machine is a lower reality version of a computer?
