How to get Gnosis?

I'm curious about the process of acquiring Gnosis, a decentralized prediction market platform on the Ethereum blockchain. Could you walk me through the steps of acquiring GNO, the native token of the Gnosis ecosystem? What kind of exchange would I need to utilize to make the purchase? Additionally, is there a specific wallet that's recommended for storing GNO securely? Furthermore, are there any considerations I should make before investing in Gnosis, such as the current market conditions or the platform's future roadmap? I'd appreciate a comprehensive yet concise explanation of the acquisition process and any relevant considerations.
