DVC distribution likely very concentrated and biggest holders those with the greatest power yet reluctance to change things. If you think current form doesn't work why [increasingly] reward holdouts? (that may include me btw). I don't get the point of conversion, but if anything the rate should get increasingly worse, not better.
I'm personally against any conversion/renewal actions.
New coin should be the new one without any "premining" heritage from old coin.
...
But, again, I'm strictly against any conversions for old devcoin. Just let it die and do not try to dig out its corpse.
The WORST thing you can do for long-term DVC members/contributors is not reward for existing holding. You would essentially be saying "So you contributed to DVC? Cool. You held your coins instead of dumping them because you believed in the project? Well, you should have just tanked it with the others because now you get nothing at all! Oh, by the way, interested in joining us on a new project?" Anyone that did this would end up with no reason NOT to continually dump at that point, because you'd be showing that it's the "right" thing to do.
You would literally be rewarding those that contributed nothing and continually dumped their free coins on the market, which is at least part of what caused this anyways (price was MUCH higher, 120+ satoshis, before a huge influx of people started getting added to the receivers. As more people were added, the more dumps occurred, which can be seen by just following its history).
