It All Began with Bitcoin! The revolution is now unstoppable! Which cryptocurrency will become the new dollar? The market of cryptocurrencies has now reached over 350 billion dollars in evaluation. It is a remarkable achievement since now this industry is bigger than McDonald's and Pepsi. If this phenomenon could be left outside the media a few years ago, now it is impossible to deny that there is a true revolution in the act. If you have never heard about the term "cryptocurrency", you might be wondering what it is. A popular definition states that a cryptocurrency is a currency that operates trough a decentralized system (the blockchain), is anonymous for the most part and it is not backed up by physical coins. It is easy to understand why so much attention is going into this space, especially since Bitcoin crossed 10,000$ in November. The general public, however, often is not aware of the fact that there are more than 1300 cryptocurrencies in circulation and that most of the are going to disappear in the next few months. There is this aura around cryptos that either showcase the next "big thing" or the quintessence of evil. In reality, as it happens most of the time, the truth stands in the middle. It is true that there are projects based on the blockchain that are scams, but this does not mean to underestimate the value of cryptos like Bitcoin, Ethereum, Litecoin, and Neo, just to name a few of the meaningful applications that have seen the light in the past two years.
