Tether: In a wasteland, think of each resource as a different asset class. Diversify so no single barrel or crate can wipe you out. Allocate roughly a third to high‑liquidity items—water and basic meds—so you can sell quickly if needed. The next third goes to stable, long‑term supplies like canned food and fuel, but keep the quantity low enough that a sudden spoilage won’t deplete your entire reserve. The final third is speculative: a small stash of high‑value items like batteries or tools, but never more than ten percent of your total pool. Periodically rebalance: if a resource’s shelf life is ending or demand spikes, shift from speculative to liquid. That way you keep a steady stream without over‑investing in any one spot.
