Where to buy smart chain BNB?

As a cryptocurrency enthusiast, I'm often faced with the question of where to acquire various digital assets. Today, I'm particularly interested in the Binance Smart Chain's native token, BNB. With its increasing popularity and utility across the Binance ecosystem, I'm wondering: Where is the best place to buy smart chain BNB? Should I go through a centralized exchange like Binance.com, or perhaps explore decentralized options like PancakeSwap? Additionally, I'm also concerned about security and whether the chosen platform has robust safety measures. With so many options out there, it's crucial to make an informed decision. So, where should I turn to acquire my BNB tokens securely and efficiently?
