A cryptocurrency can be easily defined as a digital currency. However, the concept behind the value and security of cryptocurrency is quite abstract and esoteric. Some people are confused about what makes cryptocurrency valuable and what makes it efficient as a means of storing and transferring value. Cryptocurrencies are also sometimes known as “altcoins” – short for alternative coins.
The most famous of all cryptocurrencies is Bitcoin, although there are many new contenders to the market, known as altcoins.
