How to buy original Bitcoin?

Good afternoon, I'm curious about purchasing original Bitcoin and want to ensure I'm making a secure transaction. Could you elaborate on the steps involved in acquiring Bitcoin directly from its source? I've heard about exchanges, but I'm looking for a more direct approach. Are there any specific platforms or wallets you recommend for buying Bitcoin safely? Additionally, I'm concerned about the security of my funds, so what safety measures should I take while buying and storing Bitcoin? Lastly, are there any fees or commissions I should be aware of before making a purchase? Thank you for your assistance in navigating this process.
