In a few years we will see the imminent "Machine Economy". In this new economy, a cryptocurrency like IOTA will be necessary to obtain computational capacity, storage space, electricity, data acquisition from dedicated sensors and many else, where a decentralized system may have millions of requests and processes per hour.
IOTA is one of the most interesting cryptocurrencies related to the Internet of Things (IoT) and the next-generation machine economy. Those who decide to bet and invest, could get an important return in the future. In my opinion Iota is still very cheap right now.
