I have read a post of an expert and he said that "Dont call Bitcoin is virtual money, you should call Bitcoin as "electronic filler" correctly, calling it "virtual" is completely wrong.

Since it comes from the "virtual" currency, that is the money used in a certain community, for example, you add money to the game, the money in the game is called virtual currency, and it can not be converted. Real money in real life, if so, its value will also push down.

Bitcoin is global and used to buy as much value as real money, and it can convert real money into great value, this is the world's most valuable currency."

What do you think about this opinion, bro?
