Chapter 11
Use Cases and Limits
Bitcoin is strongest when it is used for the jobs its design actually favors. It is a scarce digital asset, a neutral settlement network, and a base layer that can support simpler payment paths through Lightning.
It is less compelling when people expect it to behave like a bank app, a privacy coin, or a general-purpose smart contract platform. Fit matters more than hype.
This does not mean weak-fit use cases are impossible. It means they often require tradeoffs, extra layers, or different networks entirely. Bitcoin stays narrow on purpose so the core system remains easier to reason about.
A good mental model is simple: Bitcoin is strongest when users want durable money and credible settlement. The farther the use case moves from that center, the more awkward Bitcoin tends to become.
