bitcoin or dollars is not money, but you can exchange bitcoin with the exchanger in your country's money.

I think it is a kind of asset. Because Its price is very high now ($5500 per 1 coin). People won't call it Money. Maybe people treat it like gold, diamond or stock. 

A currency which had become an investment.
Seriously? Because of the small number of bitcoin that will be around it will become so valuable and we will be fighting to get our hands on one of it.
Actually it is happening now. It grew to a price which is unthinkable and will grow more as time flows by.
We might not be feeling it as a currency now but I am still looking forward for that day to come.

BTC like oil,has a price on his own
