How to buy PYTH crypto?

Could you please elaborate on the process of purchasing PYTH cryptocurrency? I'm particularly interested in understanding the steps involved, such as selecting a suitable exchange platform, creating an account, funding it, and finally executing the purchase. Also, it would be helpful if you could mention any safety considerations or best practices that should be followed while making such transactions. Additionally, I'm curious about any potential fees or commissions associated with buying PYTH crypto and whether there are any limits or restrictions on the amount one can purchase. Thank you for your assistance.
