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 is sold or bought in your example. People sell and buy 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 quantified 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 that something exists. That something is quantified with them, like coins. But it's not. Quantities are fake.
Why does your reasoning fail at such a simple level? You're talking about some Satoshi's system, banking system, liabilities and god knows what else. I'm not interested in those things. I just have one simple question for you.
Please bear with me as I explain slowly. I had "something" associated with my address. I went to an online exchange, I exchanged it for fiat currency (for $ 44k at current exchange rates), and now I don't have that "something" anymore. All I have left is just a address. By definition, this process is called sales. My question to you, what did I sell?
My answer to you is: nothing. You sold nothing. Take this analogy. I write down my name and "1 Zeus" next to it. I now have "something" associated with my address. I went to my neighbor, I exchanged it for fiat currency (for $ 44k) by writing down his name and "1 Zeus", and by writing down my name and "0 Zeus" next to it. Now I don't have that "something" anymore. All I have left is just my name. By definition, this process is called sales. My question to you, what did I sell?
