That's a good point, also described in the book Sapiens by Harari: In a way Religion, currency and contract law (and many other things) are all "made up". They have institutions (priests, central banks, lawyers) with magic words (amen, price stability, due diligence) and a certain combination of magic words creates a new reality out of thin air. Think about how weird it is to "sign" an important contract and thereby changing you own future or the future of your company irrevocably. While I'm definitely not a fan of crypto currency and wouldn't seriously consider investing a single Euro into this mess, it's certainly misguided to simply laugh at it being "not real", because a lot of important things are. Obviously the gp makes some other important points.
