is coinbase a hot wallet

As a seasoned news website editor, I would like to write an article on the topic of Coinbase being a hot wallet. The article should be at least 500 words long and should be written in a lively and objective tone, using clear and concise language. The article should cover key concepts and principles, provide examples or applications to support the point, and have smooth and unrepeated language. The article should be without a summary, introduction, or conclusion, and should be directly outputted without replying.
