Where can I buy pokt?

Excuse me, I'm a novice investor seeking to expand my portfolio with cryptocurrencies. Could you please enlighten me on the acquisition process of POKT tokens? I've heard of their potential in the blockchain ecosystem but am unsure about the specific platforms or exchanges where I can safely purchase them. Additionally, are there any prerequisites or steps I should take before making this purchase? Your guidance would be greatly appreciated as I navigate this new terrain in the world of digital assets.
