It still takes less time to get loan approval than it does to wire money to another nation.

I am unsure if "automation" or lack thereof is the sole problem.

A wire transfer takes a week... is this because of all the humans involved?
(and there is a lot)
or is it because the banks want to hold onto the money for seven days, interest free?
or do the banks just like money to move slowly? (make life miserable for the plebs?)

Cryptocurrency goes around the banks and the banksters.
Creating real money and real banking infrastructure.
