But if I was asked what is Bitcoin I will smile and tell the next fellow Bitcoin is the liberty from centralized dictatorship and manipulation despite it's price instability it has potentials for future security compared to the local fiat....
That last one is the most important thing. Everything else is just reinventing something that was not thought of when BTC started. It's a disruptive technology, and that should be enough. People that do not believe in it being a disruptive technology, and who need more explanation to surround it, will need to invent more uses for it. And they do so without giving the initial idea of BTC a second thought. And we are seeing that do not just with BTC but also with other crypto projects, NFTs...basically throwing anything at it and seeing what sticks.
