In my opinion, there are big differences in these two currencies. As we all know before payza, webmoney, payoneer ... it is heavily used in payment and is called virtual currency. Bitcoin is really a digital coin. It also offers superior technology, utility and innovation. A revolution to define decentralized supply is the difference.
Big difference exist, its not just your opinion. Bitcoin is crypto coin, digital coin is how would I call fiat in digital form. Technology, blockchain on which bitcoin is made is completely different from traditional system, supply is regulated different. Centralized system can't be compared with decentralized system, and that is maybe the biggest difference between this two systems, and after that almost everything else is different, supply of coins, transactions between users.
You can't compare digital currency, which is traditional currency in digital form with crypto currencies. People should stop doing that, and to learn more about crypto before starting to claim anything. There are many people who doesn't know how traditional system works, they need to learn a lot.
