So, bitcoin isn't real currency because it's price keep grow up or down ? Let's say dollar suddenly worth 25% more than before because america suddenly in good economy, do you think dollar isn't real currency anymore?
I think bitcoin is real currency, even it's price & system based on something different than fiat.
Bitcoin is real currency to me, except that it is more volatile compared to fiat. I do not use bitcoin for any purposes except for small transactions, so I do not even know if I will use the bitcoin for its actual value.
Fiat worth more to me than bitcoin, just that I prefer to use bitcoin as it is fast and almost free for online transactions.
Bitcoin is worth a lot yet worth
(opposite of a lot), since you are holding something that has value, but it is not physically there, depends on how you view it.
