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.
You want to force devcoin holders to dump all coins at the beginning of new coin?
Then there should be an enormous source of new coins for conversion of old devcoin to new ones.
I'm personally against any conversion/renewal actions.
New coin should be the new one without any "premining" heritage from old coin.
But, if new Devcoin team will reach an agreement that old devcoins need to be converted to new one - then we have to think about convertion mechanism which will help us to avoid huge dump of old devcoins through Renewal/Conversion system.
New coin will be burried alive if 16 billion of devcoin (OK, even if 10% of existing devcoins) will be "immediatelly" converted and dumped.
6 years of generation produced too much coins. Even a portion of it will kill new one once conversion system will be in place.
So the possible solution is to offer unfair conversion rate at the start of the conversion system offering much better rates for patient holders.
But, again, I'm strictly against any conversions for old devcoin. Just let it die and do not try to dig out its corpse.
