Key takeaways
- Bitcoin uses a decentralised blockchain with no central authority.
- The maximum supply is capped in the protocol.
- Crypto assets are highly volatile; total loss is possible.
01How Bitcoin works
Bitcoin is a decentralised network that records transactions in a public database, the blockchain. It needs no central authority and is secured by computing power.
02Scarcity as a core idea
The maximum supply is capped in the protocol. This programmed scarcity is a central argument for supporters, but it does not guarantee value.
03Volatility and risk
Crypto assets fluctuate sharply and can cause heavy losses. Anyone investing should factor in total loss and use only disposable capital.
04Custody and responsibility
Self-custody shifts full responsibility to the user; lost keys mean lost coins. Exchanges in turn carry counterparty risk.
