How to buy bancor?

Could you please elaborate on the steps involved in purchasing Bancor? As a cryptocurrency enthusiast, I'm interested in diversifying my portfolio and Bancor seems to be a promising investment. I understand it's an Ethereum-based token, so does this mean I need to have Ethereum in my wallet before I can purchase Bancor? Additionally, what are the recommended platforms or exchanges for purchasing Bancor tokens? Also, what factors should I consider while choosing a platform, such as fees, liquidity, and security? Finally, once I have purchased Bancor, how can I store and manage my tokens securely? Thank you for your assistance in navigating this process.
