What is the $1000 limit per day on Coinbase?

I'm curious about the daily limit of $1000 on Coinbase transactions. Could you explain what this limit means and how it affects users? Does this apply to deposits, withdrawals, or both? Is there a way to increase this limit for those who need to conduct larger transactions? Also, is this limit imposed by Coinbase specifically or is it related to regulatory requirements? I'm interested in understanding the reasons behind this limit and how it might affect my cryptocurrency trading activities on the platform.
