In the 21st century, what has changed drastically is the value of digital. Digital media, digital technology, e-commerce, and, more importantly, digital cash. Wait, what? Yes! In the 21st century, we have digital cash. More conveniently known as cryptocurrency, digital money has taken the world by storm and has been a subject of interest for many finance mavens. For a newbie, the mention of cryptocurrency can be confusing and rather valueless. However, once they begin seeing where they can invest their money and start questioning paper money, the first thing they will do is open Google's search engine and type "what is cryptocurrency?" Once you type it out, there's no going back. Cryptocurrency is volatile, but it is also smart. As long as you know what it is when to make a move and how to make a move, your wallet is going to stay satisfied.
