Fact: Bitcoin is unneeded by 99% of the world population. It's a fun experiment with limited practical use.
Saying that for the first money in history of the world is plain ignorant. Take a look at the Fiat-Gold-Bitcoin comparison table and realise it's the most groundbreaking invention since Internet.
also the point is not if it is needed or not, but if it offers a valid alternative, one could argue that for "bitcoiners" fiat is not needd at all, even today i could purchase thing directly by using btc, so why i should use fiat?
