Why is it hard to verify my identity?

Can you explain why the process of verifying my identity seems to be so challenging when dealing with cryptocurrency platforms? I've provided all the necessary documents and followed the guidelines meticulously, yet it still seems to take an unusually long time. Is this a common issue for many users, or is there something specific about my case that's causing the delay? I'm eager to gain a better understanding of the reasons behind this hurdle so that I can navigate the process more efficiently.
