I picked up a pen, wrote 2 BTC on a piece of paper, and said that I had just created exactly the same record.
There is much to be learned from this thread, even if the argumentation is not flawless.
What is the essence of cryptocurrencies? It is paradoxical, but the essence of cryptocurrencies does not lie in their electronic formit is possible to conceive of a cryptocurrency that is not electronic.
The essence of cryptocurrencies lies "in the number 2 written on a sheet of paper": this number does not represent anything else behind it (as is the case with stocks, real estate, or gold). And though, cryptocurrencies can have value - even great value ! How it is possible ?
If me or you write number 2 on a sheet of paper then it is almost impossible to market it - almost no-one wants to buy it even if the price is very low. But if, for example, Cristiano Ronaldo write number 2 on a sheet of paper (and especially if he clearly and trustworthily communicates that he do not write more than 21 000 000 numbers on paper sheets), then it is marketable and can get a great market cap. What is the difference ? The reputation.
The only source of the value of the cryptocurrency can come from its reputation. The reputation of persons/things/ideas/techniques that is tied with this cryptocurrency/asset. Often the very important part of cryptos value comes from the reputation of its creators - this is probably the main reason why the creator(s) of Bitcoin wanted to stay anonymous. They did not want that the value of Bitcoin depends from their personal reputations but from the reputation of the idea and its implementation.
