I agree with all answers that you provide about all questions and I appreciate your answer about explanation of dark pool and its working as well as you have also given the details that Bitcoin and Ethereum are also involved in dark pool because it's not necessary that all tokens are involved in dark pool trading or not as you have also cleared this concept

I am happy that you have given your answer about advantages and disadvantages of dark pool in the last question but it would be much better if you provide the screenshot in question number third and I know that many of the users feel it difficult to provide the correct answer along with screenshots but over all you make great efforts in other questions
