How to get BTCB?

How do I acquire BTCB? I'm interested in adding this cryptocurrency to my portfolio but I'm not entirely sure how to proceed. Could you please elaborate on the steps involved in obtaining BTCB? Is it possible to purchase it directly from an exchange? Or do I need to go through a specific platform or service? Additionally, are there any specific considerations or risks I should be aware of before making this investment? Your guidance would be greatly appreciated.
