Bitcoin and Digital Scarcity

Bitcoin is a decentralised digital asset with a fixed maximum supply and no issuing authority.

Learning objectives

  • Explain Bitcoin's design: a capped supply and no issuing authority
  • Understand why its price rests on demand rather than cash flows
  • State the main risks honestly

The design

Bitcoin launched in 2009 as a peer-to-peer network for transferring value without an intermediary. Transactions are validated by miners under proof-of-work, and the protocol caps total supply at 21 million coins.

No company, government or central bank issues bitcoin or can change its supply schedule unilaterally.

Where the price comes from

Bitcoin has no earnings, no cash flow and no dividend, so it cannot be valued the way a business is. Its price is entirely a function of what buyers and sellers agree, which is why it moves far more violently than broad stock markets.

The honest risk statement

Bitcoin has repeatedly declined more than 70% from previous highs and has taken years to recover. Anyone owning it should be able to survive that outcome financially and emotionally. Nothing in Study suggests you should own it.

  • Fixed supply

    A supply cap set by a network's rules. Bitcoin's rules limit issuance to 21 million coins; such rules could only change with broad network agreement.

  • Drawdown

    The decline from a previous peak, measured peak to trough.

Why this matters

Volatility of this magnitude only becomes tolerable when it is expected in advance.

Myth vs reality

Myth: Bitcoin's price is backed by something.

Reality: There is no cash flow or issuer behind it. Its price reflects supply, demand and sentiment alone.
