Couldn't the elite bankers simply buy the entire network and take over bitcoin? Aren't they so wealthy that they own the whole world?
LOL this is the funniest thing I have heard since the Banks went broke in 2008 and needed trillions of dollars in bailout money.
Wealthy? not likely, try broke. So broke they couldn't pay wages.
However, even if they were "wealthy" as you put it, they cannot "buy the entire network" for any amount of money.
The reason for this has to do with demand for "people created money" more than Bitcoin itself. People "demand" their own form of money now, created by them.
Today that looks like Bitcoin, tomorrow that could look different but one thing won't change, people have "had enough" of Banks and Governments being in charge of money creation. You can't stop this now, the cat is out of the bag, people know they can create their own forms of money.
You cannot "buy" that idea from them, they will always know.
Hope this clears up your understanding about what Bitcoin is, and what it represents.
Bitcoin is Freedom!
