How to buy crust?

Excuse me, could you please elaborate on the process of purchasing Crust tokens? As a novice in the cryptocurrency space, I'm somewhat unsure of the steps involved. Do I need to set up a special wallet? What exchanges currently support Crust trading? Is there a minimum purchase amount I should be aware of? Additionally, are there any fees associated with buying Crust, and if so, how do they compare to other cryptocurrencies? Lastly, are there any security measures I should take to protect my investment? Thank you for your assistance.
