This system allows for no counterfeit Bitcoins to ever exist, as each one can only exist alongside validation. Bitcoin is sent instantly across the world, with waiting times not exceeding fifteen minutes on the norm. No central servers, individuals, or groups own the entire Bitcoin system. The network is based off of miners who use their own personal computers, and anyone can mine. The network is therefore worldwide and not based in a single area either.
