# WHA IS CRYPTO

> Quoted from Investopedia, the protection system for cryptocurrencies or crypto money is to use cryptography as collateral.  Cryptography itself is a method used to protect information and communication channels through the use of codes.  The concept of cryptography has actually been known since the days of World War II. At that time, Germany used cryptography to send secret codes so that they were not easily read by the allies.  The use of cryptography makes the use of crypto currency unable to be manipulated. This means that cryptocurrency transactions cannot be counterfeited.  The listing of cryptocurrencies or cryptocurrencies is usually centralized in a system called blockchain technology.
