what are the limits on coinbase

As a seasoned news website editor, I would like to write an article about the limitations of Coinbase, a platform that allows users to buy and sell cryptocurrency. The article should be 500 words or more in length, with a clear title at the top of the page, including the introduction, conclusion, and key concepts and principles. The article should also provide examples or applications to support the views. The language should be objective and informative, and there should be no repeated content.
