Could you please provide me with a step-by-step guide on how to purchase Core cryptocurrency in the United States?

Additionally, are there any regulatory considerations or restrictions that I should be aware of when buying Core in the USA? I'm eager to dive into this process and would appreciate any insights or advice you can offer.
