Best would for adding value to the currency may be a bitmit in dvc? Then people may not even convert to fiat but stay in dvc to later buy something they want.
Why don't we contact bitmit and ask them to add a devcoin payment option? At worst they'll say No - but they might say Yes.
What companies "might" do is the most important thing to consider. The outcomes are endless. We can only, but always try.
