Good afternoon, as a professional practitioner in the field of cryptocurrency and finance, I have a question for you. With the ever-growing popularity of cryptocurrencies, I'm particularly interested in the transparency and traceability of transactions. Specifically, I'm curious about USDT, a stablecoin pegged to the US dollar. Can you trace USDT transactions? If so, what methods or tools do you use to accomplish this? I'm also interested in knowing the legal implications and ethical considerations surrounding the tracing of these transactions. Thank you for your time and expertise.
