What is Bitcoin?
Bitcoin is a digital currency. It's an alternative to fiat currencies, and can be used without a middleman - the bank. This means that the currency has lower fees, and is decentralized. There are also special crypto exchanges that allow Bitcoin holders to trade their coins - sell, buy, and exchange them. Frankly, Bitcoin is the world's most popular cryptocurrency!
Is Bitcoin "the best" cryptocurrency out there?
The fact that Bitcoin is surely the most popular cryptocurrency on the market does not mean that it's the "best", by any stretch of the imagination. In fact, Bitcoin has some of the more outdated "technology", in regards to what its blockchain can do. For example, Ethereum allows users to develop a whole load of different things on its blockchain - Bitcoin does not have such capabilities.
