Tulips back then, carbon credits, our currently overprinted dollar, now bitcoins. All backed by what real asset?
Because of this, statists hate bitcoins. They cannot easily control the supply as does the Federal Reserve with the U.S. dollar (enriching their friends and impoverishing their enemies). Expect to read lots of FUD articles about Bitcoins until the statists implement a way to control Bitcoins.
FUD = fear, uncertainty, and doubt.
