I hope the above post answers your questions.
If after 1 full year there are some BTCD that did not get swapped, then we will add those to our working capital.
I don't find it fair at all. Not only btc investors we are swallowing all the worthless btcd at overprice, but if for example 20 or 25% of btcd isn't claimed for whatever reasons ( i guess small alt coins have big % of lost coins,etc.. ), we get our stake diluted as if they existed.
