After buying bitcoin I get the ability to watch number on the screen.
But, you're not supposed to look your screen. You're supposed to use it as a currency. Haven't you yet acknowledged that this is the only purpose of its existence? It doesn't have any intrinsic value. It's only meant to be traded.
You can't make jewelry out of it. You can't live in it. It doesn't represent a fraction of a company. But, if two individuals agree that Bitcoin is money, then it instantly gains monetary value. And it does look like money! It's divisible, portable, durable, easily verifiable and transferrable.
I'm trying to look things the way you do and I think you're just closed-minded.
