How do you buy USD Coin?

Could you elaborate on the steps involved in purchasing USD Coin? As a cryptocurrency enthusiast, I'm curious about the process. Is it similar to acquiring other digital currencies, or does it have unique requirements? Are there specific platforms or exchanges that facilitate the purchase of USD Coin? Additionally, are there any security measures I should take into account while making the transaction? I'm interested in understanding the entire process from start to finish, including any potential fees or limitations that may apply.
