Guide 2: What is crypto currency?

Summary: What is crypto currency? 

Crypto currency is a digital-asset designed to work as a global currency for the trading of goods and services.
It does not rely on a central authority/government for management, but instead uses maths (cryptography) over blockchain technology as the means of security and control.
No single entity can influence the value and/or future decisions alone, and records cannot be changed by ‘hacking’ a single server.  
Crypto Currency allows the world to trade as they always have done, but in a manner that is suitable for today's global climate, because:
Crypto Currency can,
  • be the same currency unit all over the world 
  • be the most secure form of managing our money
  • not impacted by individual government actions.
