There will be a big influx at beginning and then crafting will be useless again after maybe a month cuz i'm guessing Turn 6-8 will be faceroll and Turn 9 will stump people for weeks.
It will be useless to top-tier people after a month. But most people aren't top tier. I think it will be profitable for 4 months, possibly more if they don't get something as market-crashing as housing.
