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)
When it comes to;
-Decentralized
-Irreversible Transaction
-Anonymity
Then its way too miles ahead if we do compare it to fiat and this is why it did really get soo much community support due into that characteristics.
For us to be noobs then its understandable that we cant grasp out everything in one go specially if we are just starting but due to experience
and more read ups then we would really be able to uncover on whats the real deal.
