Bitcoin is not just a currency; Bitcoin is money.
Money is a commodity, and in the case of Bitcoin, it is the most desired commodity by society and the hardest to produce.
Bitcoin is not simply digital; it is physical. Although it is used in the digital realm, its essence is entirely physical. The fact that we can't see electrons doesn't mean they don't exist.
Bitcoin is a block of pure energy generated approximately every 10 minutes. This energy can be measured by the number of hashes and cannot be falsified; otherwise, Bitcoin would lose its primary characteristic: its intrinsic anchoring in objective reality.
It exists only because it is NOT abstract, nor is it imaginary. Bitcoin is purely physical, and this can be verified by anyone, at any time, in a completely sovereign manner.
