How did IOTA perform in 2018?

At a time when cryptocurrency was synonymous with blockchain technology, IOTA proposed a modification.

IOTA, as its name would suggest, aspired to be a cryptocurrency for the future of Internet of Things (IoT). But its founders thought that the blockchain had “too sluggish transaction times and skyrocketing fees” to be able to power the world of connected devices. Instead, they introduced a new distributed ledger technology based on Directed Acyclic Graph (DAG) — and named it Tangle.

As a participant, when you want to make a transaction on Tangle, you need to pick two previous transactions at random, validate them, and then connect them with your own transaction. The reward for doing so would be getting your own transaction verified by subsequent participants. This means that unlike with most cryptocurrencies, IOTA transactions don’t incur any fee.
