Data is a generic term and means nothing. I can put the following data next to your name: "10 ddghjjkjgf" and then claim that you bought magical coin called Ddghjjkjgf. That's nonsense. If I claim that this coin exists I am required to show it. So, can you show 10 coins that a person with a number "10" attached to their address supposedly bought for half a million dollars?
You can claim anything you want, but will you be able to sell someone 10 ddghjjkjgf? I'm not sure, but you can try. Let me know how it goes.
By the way, I'm still waiting for you to tell me how can time or a computer program exist without anyone seeing them?
