[Nonlogs.io](http://Nonlogs.io) is a somewhat new exchange that appeared after [tradeogre.com](http://tradeogre.com) went down. It's kind of the de facto place to trade GRIN now since ogre is gone (gate seems impossible to use if American and possibly otherwise as well).
Anyway, someone’s buying XMR on [nonlogs.io](http://nonlogs.io) at $10–$40 above spot price in the XMR-BTC market.
*(*Not financial advice. Definitely risk in using new-ish exchange, but I have been using myself a bit testing them out since they are the best place to trade GRIN and WOW nowadays.*)*
