This morning I went to the bank (which I only do about once a year to update my ID), and customer service told me a transaction had been returned.
It turns out one of my international transfers had been returned because I didn't include my full address (I did, but apparently I needed to split it up into "Address Lines 1 and 2").
The bank teller took a closer look and discovered the refund was 13.3% less than my original amount! (Note: I didn't discover it, he did.)
It turns out that through this back-and-forth, fees, currency conversion, and various other random charges, I'd lost over 10% of my balance (even the bank teller was shocked).
Honestly, as a cryptocurrency founder, there's no better time to experience this kind of thing.
We're definitely going to rule the world.
