How to buy NEAR Protocol in USA?

Hello, could you please guide me through the process of purchasing NEAR Protocol in the United States? I'm relatively new to the world of cryptocurrency and finance, so a step-by-step explanation would be greatly appreciated. I'm particularly interested in understanding which platforms or exchanges I should use, what are the necessary prerequisites, and if there are any specific regulatory considerations I should be aware of when making such a transaction in the US. Additionally, if you have any tips or advice on how to safely store and manage my NEAR Protocol holdings, that would be invaluable as well. Thank you for your assistance.
