There’s still confusion among the general public about how or why cryptocurrencies are necessary.
Check this out for an example: a $10 billion transaction was sent using XRP (Ripple), for a total transaction cost of 0.000012 XRP (merely pennies).
Compare that to any percentage that a bank, or Western Union, etc, would charge, and you have a heck of a reason to use XRP instead of the traditional banking system!
Here’s details of the transaction at the Ripple blockchain explorer: https://xrpcharts.ripple.com/#/transactions/90865CCC92C9E24B5F027EEE0779989F23F7FA17BA75946BAE9507AB62C66595
