IOTA is supposed to be using a "Tangle" instead of a blockchain. There are no transaction fees, instead to get confirmation for your transaction, you have to verify 2-3 other transactions. It is targeting Internet of Things (IOT), hoping to be the way sensors and other smart devices report to each other and back to the main network. I bought some at $0.66, and they immediately dropped to $0.40, lol. I'm still going to hold them, but like others have stated, they have no actual use case right now, and all price growth is fueled by speculation.
