This just shows how important it is to understand concepts from first principles as opposed to trying to reason by analogy.
Bitcoin isn’t gold, and although it’s heralded as digital gold, the truth is that it’s much more than that. It’s a network of computers, called nodes, which all contain a synchronized copy of the full history of all transactions ever made on the network. These nodes are aided by miners who compete to solve complex cryptographic algorithms to validate transactions made by users on the network. The miners make sure that the bitcoins being transacted are in fact bitcoins, and not counterfeit.
Essentially, the Bitcoin network is an entire monetary system that operates on its own.
If you’re wondering what to compare the Bitcoin network to in order to estimate its valuation, then take the sum of the value of the monetary systems of the countries which it was created to replace and discount it by some percentage to account for countries that choose not to adopt the standard (like Nigeria).
And if you are in the camp that believes humans will inevitably colonize space, then you should be invested in Bitcoin, because rest assured that the current monetary systems in place don’t scale beyond singular nation-states. Colonies on Mars aren’t going to be okay with relying on central banks back on Earth to control their money.
