The idea behind all these cryptocurrencies is indeed very interesting ! I never thought I would be interested in these kinds of things, but here I am ! There is so much to learn here on steemit and I hope you will enjoy being here with this community :)
yeah its something really new ( well not THAT new ) but the concept has not been there up to now. We are using the physically touchable kind of currency since i dont know how many thousands of years....
