Given the user mentioned part 2, it's likely that part 1 would cover the initial emergence of the market, and part 2 in 2021 would be a continuation. So for the essay, the structure would involve introducing what Yapoo Market 65 is (a dark web market?), discussing its operations in part 1, and then in part 2 covering its events in 2021. However, since the user wants part 2 from 2021, I need to focus on that year's developments.
