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)
The first time that i ken about bitcoin whas back in 2011 when i saw a report on the TV about a guy mining bitcoin and earning money from it, at first i didn't pay it any attention because i was young, but a couple of years later i came across it again when searching for a way to make moeny online, at first i thought it was complicated but after a while i learned the basics and quickly came to realize of how great and convenient using bitcoin is , and i still think about what would have happend if i invested in it earlier.
