The real question in my mind is how much actual demand there would be for the DEC bonds concept. Everyone already knows that a ton of DEC will be required for things in the future, and if they buy now they can get it at ~62 cents on the dollar, but hardly anyone is taking that deal. DEC bonds would just be giving a larger discount, but with the downside of locking up the DEC, as you mentioned.

So if hardly anyone is taking the deal now at 62 cents on the dollar, then if we offered them for 50 cents on the dollar (which is roughly what it would be with your 800k DEC bonds gets you 1M worth of DEC example) would that really cause any significant amount of buying? Enough to make it worth the development effort of selling the bonds and then including them as payment options for everything that uses DEC in the future?

This is what I'm not really sure about. Also, the alternative is just to be patient and wait for the new DEC sinks to be released over the next 6 months or so. At the moment I'm leaning towards just being patient over creating additional ongoing development for something that I'm not certain will have that big of an impact.
