One of the best use cases i found is Global Access:-

3 Reasons why:

1. Zero Cost overseas transfers:

Elimination of all the margins and commissions charged by banks just for sending money overseas.

1. No more current exchange rates:

No need to keep track of exchange rates. This will ultimately lead to some unity and uniformity in global finance.

1. Simpler transactions:

No more legal compliances, exchange markups, forex charges, bank commissions, exchange rates, currency conversions, different monetary policies for different countries, and list goes on.
