I started investing in Ethereum when it was only about $400, I also began mining the currency shortly after. I mainly use the currency as a way to exchange for other upcoming cryptos that I wish to support, other than that I just hold the currency because its always enjoyable to check if its up or down on that day. Although I myself have not used the blockchains advantages for creation, I do wish to learn more about how to use the currency other than mining or investing. As a person who mines the coin I do enjoy and support the direction this currency is heading for the future, therefore I will continue to give my full support to trustworthy crypto currencies whether upcoming or well rooted.
