So potcoin will take about another year to mine out at 420,000,000/40/420.
I really believe that had POS been popular when this was launched that it definitely would have gone that route.
To be completely and totally honest with this opinion I'll also state that I don't really hold any significant amount of POT anymore.
That said, dogecoin should be a lesson learned for this potcoin devs. Dogecoin has by far and away the largest community and because of the multipools mine/dump etc the price will never be stable until it is all mined out, which technically is never but with the tiny block reward it is unlikely to be worthwhile.
Blackcoin should also be the same lesson as we'll all learn within a month or two. Going POS without a wide enough distribution may result in scarcity driving price but may also result in a lack of interest and a lack of new miners or investors or most importantly... those who are both.
TLDR the devs should look at the wallet distributions and consider moving to a mixed POS for this coin and greatly lowering the block reward.
You want the value of the coins to be in the wallets of the coin holders, not subject to the whims of the multipools.
Every scrypt coin goes through this. If we change algorithms we will just got through it again when asics hit that algorithm too.
I do like the idea of transitioning to a POS system though, especially as we approach the 420 Million coin limit. I think that could be a major selling point to merchants looking to accept the coin. They don't necessarily want to cash Potcoin out for USD or Bitcoin in a POS system. They could increase their coin's value by holding it until its ready to be spent, much like interest on a Corporate bank account. That could be appealing to a lot of merchants.
