Im selling my grain right now as I noticed the exchange rate keeps slightly getting worse so may be best to plow as much though now for dec as possible and add maybe 25% to the LP as you go to build it up and not lose the fees when you swap eventually. I think there will be way to much grain and anyone self sustaining like myself with extra grain will be offloading it and also many people have millions of grain that they could offload at any moment but I doubt the market has the capacity yet to absorb it so im trying to cash out as much as i can as often as i can before something happens where grain gets more devalued as until land 2 comes out grain will likely be very low cost as it really doesnt have a use other than for research and sps production.
