Why can i only buy $100 on Coinbase?

Could you please explain to me why I am restricted to purchasing only $100 on Coinbase? Is there a specific limit that applies to my account, or is it a general policy? I'm curious about the reasons behind this limitation, and whether there's a way to increase it. Could it be due to my verification status or the level of my account? Additionally, I'd like to know if there are any alternative platforms or methods that might allow me to make larger purchases of cryptocurrency. Could you provide some insights into this matter? Thank you for your assistance.
