How do I buy an asset mantle?

Could you please explain the process of purchasing an asset mantle? I'm quite interested in investing in this area but I'm not entirely sure where to start. Could you guide me through the steps involved in making such a purchase? Also, what factors should I consider when selecting an asset mantle to invest in? Are there any specific risks or challenges that I should be aware of? I would appreciate your insights and advice on this matter. Thank you in advance for your help.
