The goal of the IOTA Foundation is it to build a flourishing Machine Economy, where machines seamlessly interact and transact with each other. With IOTA, we have introduced the first scalable distributed ledger architecture that has no transaction fees and is able to run in the Internet of Things environment. The power of IOTA is in its network, as it scales horizontally with the number of network participants transacting with each other.
Free and instant transaction. Fully scalable.
But everything has a price. Looks like iota price is very expensive
This scalability drama is just ridiculous. An stupid idea which became a marketing z to make fools by shitcoins and stay away from bitcoin because it is "old slow and expensive "
