How do I buy Dex?

Excuse me, as a cryptocurrency enthusiast, I've been hearing quite a buzz around the Dex token. However, I'm a bit perplexed on how to actually purchase it. Could you possibly enlighten me on the steps involved in acquiring Dex? I've heard about various exchanges, but I'm not sure which one is the most reliable or suitable for Dex trading. Additionally, are there any specific wallets that are recommended for storing Dex safely? Your guidance would be greatly appreciated as I'm eager to add Dex to my portfolio.
