IOTA is a cryptocurrency designed for the Internet of Things. But before we get into why the Internet of Things needs IOTA, lets look at what IOTA can offer to the existing cryptocurrency scene. (Don’t worry, we will return to the internet of things later). IOTA has 4 HUGE advantages over Blockchain cryptocurrencies in that it is:

Scalable
Decenteralized
Modular
Fee Less

So I think it's very interesting to invest in.
