Pros
It has all the uses that any other transaction-based currency in crypto space has, but it is easier to use because of its stability.
It was only deprecated in June 2016, but with great difficulty, it was brought back to its peg within 3 months. The founder forced all the stops to bring it back to its 1 US dollar peg, and the circulation supply became more than 1/4 of its previous price!
Cons
It is ranked remarkably low in terms of market cap globally, going far below even the first 1000 cryptocurrencies worldwide.
