The first time I came into contact with BTC, I felt that there was little difference between e-payment and BTC. However, with the gradual understanding, e-payment and BTC are becoming more and more different.
In essence, electronic payment is the circulation of legal currency in one or some countries, while BTC is the circulation all over the world（ If every country agrees)
First contact with BTC, what is in my mind is i can buy mobile data, or maybe pay electricity bills with money that i can earned online. At past there are a lot of site in my country that allow us to deposit BTC (although it is converted to fiat automatically) but with that i don't need to go to shop or maybe no one around me can know i can earn money online and buy digital product by myself.
