Devcoin was launched on July 22, 2011. For six years there are nearly 16 billion of Devcoins.
In order to renew old Devcoins at the rate of 1 satoshi it will require about 160 BTC or about USD500K.
This is just for conversion/renewal alone.
What we need to do to avoid DVC flood for DRS?
Lets make conversion rate to rise gradually over time. It means the later you apply for a conversion - the better conversion rate you have...
Way too complicated and will work counter to your objective.
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.
Either just apply distributional changes to existing, or move on to fundamentally new.
