the obvious problem with the swap at this point, is that the amount on bittrex is 1.3 million higher than what it should be.
someone bought all those coins and would now like to swap them please.
if the Dv3 coins are still available for swap and not stoled by whomever dumped D2, then maybe there needs to be a lower ratio for swapping :p
this is the obvious simple way to move forward with existing chain.
although with the masternodes not working, there does need to be a hard fork so it's potential that another 1.3 million (or whatever) are mined/created.
neither solution seem happy
but at the same there is also the fact that 100% swap will be unlikely to happen. not everyone will be paying attention (from the whole process) and there will be coins on wallets somewhere else that people will be ignoring too.
..
perhaps the way could be to set up an auto process to swap versions at lower ratio, then at end of period, all remaining coins to be divided among those receiving the lower ratio.
to further create trust, then either sending old droidz direct to burn addresses so they are immediately gone, or stopping the chain and using a static distro list (assuming then that bittrex coins are out of the entire process at that point).
this page to create burn addresses seems to imply that it should be easy to create a few hundred unique burn addresses
