Very good explanation, great illustration
I recently tried to send money to my friend in Nepal.
WU was to expensive, he can't use paypal in his country, can't get international VISA card (only for use in India&Nepal), Bank wire fees also was to high (and to long wait to receive money) etc.
On the end I suggested to him to open BTC wallet and we solved our problem
It's really simple, fast and secure process.
Thanks God for bitcoin
