Bitcoin will be the last money. It is the bridge from our current slave state society into a free and prosperous society that eventually evolves into a a zero point energy society where money is no longer needed. Humans will have ascended enough consciously by this point that we no longer need the 3rd dimensional system of money when we are living in the 5th dimension and higher. This evolution is over 1000’s of year so money isn’t going anywhere anytime soon
