11. Bitcoin pros and cons
Bitcoin has a number of advantages:
 Bitcoin is the first cryptocurrency to capture the public imagination
 Total issuance is limited to 21 million, so it is unlikely to be devalued
 As a decentralized currency, Bitcoin is free from government interference and
manipulation.
 Transaction costs are much lower than with conventional currencies.

12. Bitcoin pros and cons
Bitcoin's disadvantages include:
 The price of a Bitcoin has been increasingly volatile, making it difficult to assess its
real value and increasing the risk of losses for investors in the cryptocurrency.
 The relative anonymity of Bitcoin may encourage its use for illegal and illicit
activities such as tax evasion, weapons procurement, gambling and circumvention of
currency controls.
 The fact that bitcoins exist primarily in digital form renders them vulnerable to loss.
