What is power?

OK so the trillion dollar question is, what is power? And also… How does one gain more of it, etc?

So I think the basic idea is people think that power is money but this is actually not necessarily true. Perhaps the deeper insight is capital is power. 

For example capital could be like owning gold, valuable real estate, or the most Apex of them all, owning bitcoin– which is the true digital capital of the 22nd century and beyond.
