Right now if I wanted to run a business incorporating crypto on my own, frankly it would be a bit of a nightmare(no pun intended). When I receive .000XYZ and keeping track of what the P was at that time, compared to when I sell or use the currency could take days if I do volume. Its almost like a barrier to entry, or at least a damn that is slowing adoption down.
How? It's no different from dealing with foreign currencies, and literally every company that does business internationally already has that all figured out. Fluctuating exchange rates are not actually a difficult concept for businesses to grasp. If you think it's difficult, then maybe you shouldn't be running a business.
Is there a movement to get this type of info associated with each transaction ever made ?
No. The price is independent of the transaction itself.
