One word: math.
Bitcoin is based on math. It has finite supply
World economy is based on trust.
What Bitcoin "created" so far is a lot of victims who lost money to thousands of scams and even "genuine" products like LUNA brought more victims into this world.
The average Joe needs to trust the system, not to be afraid of it.
When you get more and more and more victims, and it's only rolling like a giant snowball - then no math in the world can save it. And this is where we're heading now.
