Have you ever heard of bitcoin? Well, Ethereum is going to be similar to bitcoin and it is going to be a platform where you can mine coins known as ether. 

Ethereum is a new platform that is going to continue to develop and all of the users of Ethereum are going to be a part of history as it continues to grow. 

Ethereum will allow you to mine much like bitcoin, however, the sad thing is that it is still a digital currency that is not accepted everywhere. Although, when it is accepted, you are going to have the digital currency built up and will not have to worry about jumping on the bandwagon because you were already on it!
