I was a bit scared after just checking the on-chain records earlier... A couple of days ago, I even thought a "coincidental transfer" was just a slip by a random person: the amount was very round, the timing was close, and it looked completely random. As a result, today I followed the address relationships step by step and found that the path was actually quite "logical": first a small exploratory transfer, then a few segments looping around, and finally returning to a cleaner exit address. To put it simply, it’s not a coincidence, but a test to see if you’re too lazy to follow up.

And coincidentally, there was a discussion in the group about whether privacy coins and mixing coins are considered original sins. My feeling is: the technology itself is neutral, but the boundaries of compliance are very blurry, and ordinary people are most likely to stumble. In the future, when I see such "too perfect" transfers, I will pause first, look at the on-chain footprints a bit more carefully, and prefer to go slow rather than take shortcuts. That’s all for now.
