Could you elaborate on your inquiry regarding whether you want "DCR on"? It seems you're referencing the activation or utilization of some cryptocurrency feature or service related to Decred (DCR), a decentralized cryptocurrency. Are you asking about whether you should activate a specific feature in your wallet or exchange that relates to DCR? Are you considering investing in DCR tokens? Or are you wondering if you should turn on a certain setting or functionality related to Decred's blockchain? Clarifying your intention would help me provide a more tailored response.
