✒ The author suggests that cryptocurrencies lies in the intersection of three fields:

  1. cryptography (to ensure the integrity of transactions);
  2. game theory (to establish consensus on the state of the ledger); and
  3. economics (to design proper economic initiatives).

From another perspective, one can argue that those who invest in cryptocurrencies are a combination of:

  1. Macro-economist (those who understand how money works);
  2. Cypherpunks (those who understand how protocol works); and
  3. Speculator (those who understand how psychology works).
