The global economy is definitely moving towards an eco-digital system. From investment to transfer of money, everything becomes paperless. The newest and most promising addition in the digital payment sector is cryptocurrency. Cryptocurrency is a medium of exchange like a normal currency like USD, but is designed for the purpose of exchanging digital information. Cryptocurrency is defined by Investopedia.com as a "decentralized digital or virtual currency that uses cryptography for security" making it difficult to fake. Because it is not issued by the central authority, the government cannot take it from you. Blockchain is the reason why cryptocurrency has any value. Ease of use is the reason why cryptocurrency is in high demand. All you need is a smart device, an internet connection and instantly you become your own bank making payments and money transfers.
