What are "fake tulips"? There are many types of flower, but I've never heard any described as fake tulips. And why grow fake tulips when you can grow real ones?

And why is a decentralised ledger even relevant to tulips? They're not bits of code, they're real things you own irrespective of whether other people know you own it.

Also, you need to distinguish between the blockchain technology and the value of bitcoins. Blockchain does not depend on bitcoin. Bitcoin can fail while blockchain continues to change the world.

The real value of bitcoin at this moment comes from trust that the hype will continue. It might. Or it might not.
