How do I buy Multichain?

Hello there, I'm interested in purchasing Multichain but I'm not entirely sure how to go about it. Could you please guide me through the process step by step? What platforms or exchanges support the purchase of Multichain? Do I need to set up a special wallet to store it? Are there any specific regulations or limitations I should be aware of? I'd appreciate any information you can provide to help me make an informed decision. Thank you in advance!
