Hello for those who do not know me I have a Youtube channel and I am researching to upload a video tutorial on PAPER WALLETS, it is very easy to create and use your own paper wallet.

The problem is to do it safely that if you take a minimum security measures you can not steal your BTC from your Paper Wallet.

But my question is this: "When I generate my pubic wallet address and my private key at the beginning of the paper wallet, are these addresses already created or are they created by the same paper wallet?"

I do not know if I have explained myself well because my language is Spanish, but it is still difficult to explain the question, because if you are given the option to create your public wallet address and your private key, WITHOUT INTERNET CONNECTION. So my question is if these addresses and passwords are already created before, because if you create them new, how can you create it without an Internet connection?

And if they are accounts created previously or not, another question is how do I know that nobody is going to receive my same private key due to coincidences of life? or that I receive the private key of some other person?


I hope you understand my questions and thanks in advance.
