How can I buy IOTA?

As a cryptocurrency enthusiast, I'm curious about the process of acquiring IOTA tokens. Could you please walk me through the steps involved in purchasing IOTA? I'm particularly interested in understanding which exchanges support the trading of IOTA, as well as any specific requirements or considerations I should be aware of before making a purchase. Additionally, I'd like to know if there are any recommended wallets for securely storing my IOTA tokens once I've acquired them. Your guidance in this matter would be greatly appreciated.
