But I did not sell my address in the system. I still own the address.
To say "nothing" cannot be factually correct, because logic dictates that I obviously sold something. I owned "something" that, after the sale, I no longer own. I ask you again, what did I sell?
You asked what you own. You own an address. Like everyone that installed a wallet application. That's all that you own.
I also asked, what did I sell? Obviously, I didn't sell the address, I still own it. But I sold something. What is that?
Why is it so hard for you people to look at what is actually happening? Nothing is sold. Factually, the system just plays with the numbers according to some protocols. Can you comprehend the reality of that? Nothing was sold or bought. You sold or bought liabilities in the banking system. Liability is the type of money. Operation with the numbers in the banking system means quantifying liabilities. Liabilities are existent things in the banking system and are qualified with the numbers. In the Satoshi's system there are neither liabilities nor some other type of money. Only fake quantities. These quantities fool many people by creating the illusion tha something exist. That something is quantified with them, like coins. But it's not. Quantities are fake.
