Oh, and I've had more than 300 transactions on Bitmit by myself, so the total number is a lot higher than that. If you add together the feedback scores of all the sellers you listed, and added something like 50%, I think that would give you a more correct idea about the number of transactions. If you were a Bitmit user, you could also look at the internal order numbers.
Did that. The total amount of feedback is probably around 1400-1500. I am looking at positive feedback numbers, so I'm getting an approximation. If you've sold 300ish items, that means that your seller feedback represents about 2/3 of what you've sold since you ahve abotu 200 pieces of user feedback. So if that's the case, and that's consistent accross users, that means that this analysis is abotu 50% off, which still puts the total number of transactions on the site at between 450 and 1050, which is a big range and a higher number, but still a tiny number of transactions that have been facilitated.
