so will BTCD stop producing new block on the 15th?
Don't think so, it can live on after a year has passed. The rate you get for swap will drop throughout the swap period I believe to compensate for new coins introduced, at least that's the only way I see it working. After a year you can't stop so it won't matter.
so for the Total BTCD swap: 8392.727 BTC is that included for the amount of BTCD generated for the next 1 full year?
so based on what you said, it is better to swap KMD as early as possible, since the KMD will be lesser if you swap it later?
