Looks like 25 pure, most likely to a private inv.

https://bot.tf/stats/listings/4O9K18VJ - the bot that sold for 30 was selling for 27 earlier when there was more market competition. 30 sale was pure so can't cap the buyout, but also shows that 30 flat is high.

https://imgur.com/a/eduZCd9 - current market, qs.store still at 30.5, buyers up to ~24

Personally I would be fine with 25 - 30 here since there are 2 sale that are almost guaranteed to be 25 (zols + paradox's) but you might want to double check with a price mod whether that is enough proof (particularly the paradox sale of a group of 25 pure and a b/o of 25) since neither are 100% traceable. I would argue that the chance that neither sale was 25 is <1% though.

Going with 25 – 30 keys
