Why can I only buy $3000 on Coinbase?

Could you please elaborate on why there seems to be a limit of $3000 on the amount I can purchase on Coinbase? Is this a general restriction for all users, or is it specific to my account? Could it be related to my verification status, or are there other factors at play? Additionally, is there a way to increase this limit, and if so, what steps would I need to take to do so? Thank you for your assistance in clarifying this matter.
