How to buy Filecoin?

Could you please elaborate on the steps involved in purchasing Filecoin? I'm a newcomer to the cryptocurrency world and am interested in understanding the process. I've heard of Filecoin's potential in decentralized storage, but I'm unsure of how to proceed. Could you guide me through the process from selecting a reliable cryptocurrency exchange, creating an account, funding it, and finally placing an order to buy Filecoin? Additionally, are there any safety measures I should take into account to ensure a secure transaction? Thank you for your assistance.
