I will not accept that you gave me 10 eggs if you didn't actually give me 10 eggs, nor will I accept that you gave me 10 Ferrarris if those cars are not in my garage and I have possession of the key that turns them on.
If you say you give me 10 BTC or 10 bitcoins though, I will also not accept that you actually gave me 10 bitcoins until I see the quantity in my wallet, verified by miners. If it's nothing to you, I could care less, because to me, it is something.
But until I can verify in my address that I control, that I have the private keys to, that the transaction was confirmed in a block, then you did not send me any bitcoins.
At this point, it is irrelevant what the US dollar (or fiat) price is of those bitcoins. If a block explorer does not say I have it, you did not send it, then I don't have the bitcoins. If my wallet software (that does not look too fancy as I just use either Bitcoin Core or Electrum) does not indicate the addresses contain bitcoin, then you didn't send me any bitcoins.
Beyond all this discussion, it becomes either academic or moot or pointless as most of us don't have time to explain anything else to you. If it's being talked about, that's something, not nothing.
Interesting. So, you will not accept my statement that you have 10 eggs if I didn't actually give you 10 eggs. You will not accept my statement that you have 10 Ferrarris if those cars are not in your garage and you have possession of the key that turns them on. Nor will you accept my statement that you have 10 BTC is the quantity is not in your wallet. Ok. Then I have only one question for you: why then are you accepting Satoshi's statements that you have xx BTC if you never actually saw BTC, but only Satoshi's quantity statement - "xx", and name "BTC"? Because quantity statement and name is something that you recieved from me as well: "10", "eggs", "10", "Ferraris", "10", "BTC". And I have no problem arranging for you to have them verified on the blockchain and to get you private keys and address that you control. If I arrange all that will you give me xx USD for the quantity statement on nonexistent Ferraris? If not, why are you giving xx USD for Satoshi's quantity statements on nonexistent BTC?
