1) It is likely that having mining activity continued till the time the maximal 2.8 million Joincoins is reached and without doing anything else is still one of the choice.

2) I would intend to make as little changes as possible after finding difficulties in adding new wallet features ( for such a unprecedented all-algo POW cryptocurrency) unless someone can come out with enough time, competence and confidence to lead the Joincoin forward.

Without setting up new features, the Joincoin has to find ways to have market place and other activities integrated through 3rd-party platforms which could be still problematic.

3) To have mining continued, there is no choice other than cutting down Block rewards in the end to continue it forever; otherwise mining has to end anyway.

I would be more worried about not being able to support price during accelerated mining; during the time of lowered block rewards, the price would be easier to keep or rise (due to decreased amount of new coins mined/sell pressure) and could be even more profitable than what we have now.

The problem at #2 above still stays.

4) That's why I would have been more in favor of the switching to POS (which could not be done) (or as suggested by you, swap to POS- still hard for me, as I do not have the time- which still can be considered if any arrangement can be done).
