Paper money is relevant in the future through bitcoin transaction.
I dont think paper money will be remove in the future as this is
being used already. However, lets admit thats its really helpful
to all bitcoin users.
In the future bitcoin is still here while paper money is also here, nothing will change as they are both partners for success. The fact must be accepted that we can never replace paper money with our very own bitcoin as we are just a small group in the crypto whose still under the watch of the government.
