I'm right here with the OP. I leveled miner to 43 - NOTHING is selling, even when I set the prices crazy cheap. That doesn't generate new gil though, only takes it from one player to me and sends 5% into the void. I've leveled goldsmith to 31, and sold a few things. I was at 50k, back up to 80k, back down to 49k not even 12 hours later. This game doesn't let you generate gil enough to sustain yourself. If items were actually sellable to a vendor I could actually make some profit.
