How can I get my BNB?

Could you please elaborate on the process of acquiring BNB? I'm quite interested in obtaining some but am unsure of the steps involved. Is it necessary to create an account with a specific exchange? Or are there alternative methods available? Also, what are the associated fees and risks that I should be aware of? Would it be advisable to wait for a certain market condition or can I proceed with the purchase anytime? Your insights would be greatly appreciated.
