Right. I can just send you Satoshi's words on it. Satoshi said via his software that BTC exists, and you all blindly believe him that it does by exchanging his words in a digital form.
Right, I'll believe you when you can show me the transaction ID on the software, not here on this forum. That kind of "declaration" would be enough for me if I can view in a block explorer or the wallet software that it has declared some blocks or confirmation.
Otherwise, I don't believe you, you have not sent me any BTC.
If you'd like, send me a PM and I can give you an address not in my profile and I will confirm if you send any BTC to that address.
