        What is Bitcoin? Bitcoin is a digital currency created in 2009 by an engineer, Satoshi Nakamoto. It is the first decentralized digital coin you can send through the Internet. Compared with other currencies, there is a lot of advantages. It is transferred directly from person to person without going to the banks. This means the processing fees are low or zero especially when you use it among different countries. And your account can never be frozen. 
        Bitcoins are generated all over the Internet by “mining.” Bitcoin mining is the process of making computer hardware, like GPU (more powerful than CPU), do mathematical calculations for the Bitcoin network to confirm transactions and increase security. As a reward for their services, Bitcoin miners can gain the bitcoins for the transactions they confirm. To put it simply, if you share some of your own computer facilities, resources or data to help solve the problems on the Internet, you can earn bitcoins in return. 
        Bitcoins are already used in daily life. You can use it to buy many things like video games, or gifts. One couple, Austin and Beccy Binham-Craig, even traveled around three continents during their 101-day honeymoon and paid for everything with bitcoins, from rent, food to gas. With the rising worth of Bitcoins, it seems to be more and more popular in the future.
