> <@alexanarcho:matrix.org> realize that "anonymity set" is always relative to a starting point. if i send xmr from binance to my wallet, binance knows the true spending output, since it is their wallet. if i then send the xmr to  somebody else, my anonymity set is 11 (as ring size is 11). the following tx has anonymity set of 121 (11x11) and so on. 11² essentially.

That sounds right off the top of my head
