I think in the past feedback became confirmed when partners had traded a total of 1 XMR and then this was changed later to the equivalent of 100 USD? (which makes sense as it’s a more stable currency and therefore more meaningful). I’m not sure when that change took place but I noticed one of my confirmed feedbacks disappeared a while ago, which got me thinking - was it because it was over 1 XMR but under 100 USD at the time of the change, or was it because the system only tracks the traded volume in XMR and the price of XMR dropped?
In other words, does the system base what is confirmed-feedback on the amount traded in USD-equivalent at the actual time of the trade or just takes the total XMR traded between partners and converts it to USD at whatever the exchange rate happens to be at the time?
I hope that made sense. I’m a little tired writing this at the moment.
