I totally agree with this, bitcoin provides a fast and transparent banking service for millions of people around the globe, apart from helping the u banked to use banking service, bitcoin has money electronic transactions much more easy and safer, no need to wait for 2-4 business days before the money u sent wil get to the destination, with bitcoin in a matter of minutes(high priority tx) it will reflect in their wallet, which is great waiting 2-4 business days is no longer the faster way to transfer money online, just like when phone texting was invented and killed written letters.
I remembered one time last year when Nigerians were protesting against their government,and the government blocked their fund raising Bank account they switched over and used bitcoin to raise money for food and other stuffs the protesters needed to keep the protest going until their demands are met by the government.
