A single large spike of stop-loss sales of a commoditiy that happens at the moment the commodity touches its previous three month low during a long downwards trend does not prove anything about the suitability of the commodity as a currency and is irrelevant to Krugman's argument. Without additional evidence that the exchanges are related to larger exchanges of bitcoin for goods and services, large sales on an exchange only show that would-be hoarders may be losing faith.
