They are actually all money but the big difference is Bitcoin the users are few while money we all use it. In the current situation only money is legal while bitcoin is not legal in some countries, so basically you can see that bitcoin is weaker compared to real money.
I disagree. First, there are only a few countries where Bitcoin is illegal right now. Second, we all can use Bitcoin, but we can't use other currencies except for our national currency. The main difference between Bitcoin and "real money" is that Bitcoin is rising with time and those "real money" are falling in their purchasing ability.
I totally agree with you. Bitcoin can not be weaker than real money as it is used worldwide and FIAT currencies are only accepted in local regions. And moreover, Bitcoin price keeps going sky-high while Fiat is slowly dropping.
