I have thought about money quite a bit in a 5D reality and the best answer I have been able to come up with is that it does not exist.  In a life of abundance where everything is plentiful and we can manifest  our needs and wants why would we need money?  Money is used to achieve our needs and wants in the moment and the balance is hoarded for future needs and wants.  We will be living in a reality of One and all the money in circulation will belong to the One, therefore, money will not be needed.  It will become obsolete.

Money will be critical to get to 5D but it should be shared among everyone so everyone can survive the journey.  Love your neighbor and God speed.
