What is DAI good for?

Could you enlighten me on the utilities of DAI? I've heard quite a buzz around this cryptocurrency, but I'm still trying to grasp its exact value proposition. Is it primarily used as a means of exchange, or does it serve some other specific purpose within the crypto ecosystem? Moreover, how does it differ from other stablecoins? Is there a unique feature or advantage that DAI offers that sets it apart from its competitors? I'm eager to understand its role in the broader financial landscape and how it might fit into my own investment strategy.
