Internet is used by nodes to store fake numbers. Without the internet there wouldn't be bitcoin fraud.
I didn't ask you to tell me what is Internet compared to Bitcoin. I asked you to tell me how can you prove that Internet exists? If you can accept the fact that Internet is used for two computers to communicate, then Bitcoin's proof of existence is the fact that it is used to trade.
Internet is computers and communication protocols. Those exist. Bitcoin is not "used" given it doesn't exist. Numbers are attached to address by Satoshi's system. Attaching numbers is a proof that numbers are attached. Attaching letters is proof that letters are attached. Attaching a picture to a email message is proof that a picture is attached. No bitcoins magically emerge by attaching one thing to another. You believe in some sort of alchemy. Try to use your brains for a second instead of repeating the same nonsense over and over again.
Your level of ignorance is astounding.
The Internet exists. Okay, I agree. But does the DNS protocol exist? It is also just a collection of numbers attached to addresses by your definition. Denying the use of Bitcoin is the same as denying the use of DNS. You can't see it, hear it, or touch it, yet it exists and billions of people use it every day.
