To understand Bitcoin you must first understand central banking.

I have found that a good way to approach the topic is to imagine a hypothetical game of monopoly where behind the scene you are printing more monopoly money for yourself and using it to buy up all of the properties on the board. In this scenario even a child can see that the game is rigged yet for whatever reason many people have a hard time applying this logic to the actual economy which works the exact same way by design. People can see that the houses are getting more expensive but they do not understand the mechanism behind it, or why huge investment funds can buy up so many houses when they cannot afford even a single one. They don't understand that those nearest the printer win the game and that the only solution is not to play.

Bitcoin creates a new game where everyone is equal and you can compete on even footing. It eliminates the dishonest player from the board.
