Cryptocurrency is what it sounds like - computer money. It is made by people, stored and traded digitally, and usually is not under the influence of the government. People are so interested about it because it screams “technology” and it fluctuates so much that an investor could gain (or lose) huge overnight. Bitcoin, first released as open-source software in 2009, is the first decentralized cryptocurrency. Since the release of bitcoin, other cryptocurrencies have been created.
