Since the coins per block reward was halved, I am happy to see that POTcoin has become more stable.
If POT can maintain stability for the next few months, POT will gain respect and become an attractive currency for serious business.

As of today, I do not see a need for another halving.
Mining and dumping still occurs, but it has been greatly reduced.
One more halving might not be a bad idea, but not yet.
