How to get 1 BNB for free?

Could you please elaborate on the methods available to obtain one BNB token without spending any money? I'm interested in learning about any legitimate ways to acquire it as a freebie, whether it's through promotional offers, referral programs, or any other means. Is there a specific strategy or series of steps I should follow to increase my chances of successfully obtaining BNB for free? Additionally, are there any potential risks or limitations I should be aware of before attempting to acquire BNB through these methods? Thank you for your assistance in clarifying this matter.
