Peter R's chart doesn't show that because: 1. it doesn't show causality, and 2. there is no way to know whether the transactions and/or addresses in use on the Bitcoin network are users or investors. A huge amount of Bitcoin activity is investors, probably a majority. Really, who "uses" Bitcoin? Who used it last November-December when his chart showed both the metrics and price skyrocketing? A better interpretation of his chart is that investors drive market cap!
