You have explain your understanding of crypto trading which is the buying and selling of digital assets. Something was wrong with the way you started the entire writeup my friend. I was a bit confuse in the introductory part of it. Example this

Figure 4 shows historical data of global market capitalization and 24-hour trading volume

I was looking for the figure but couldn't find it in your article. You should have eliminated the introductory part and move straight into the questions. It as though this part of introduction was copied from an entirely different source. I hope you take correction and do the needful next time.
