How is the testing going for PoW2?
Quote from one of the developers on slack;
Development of PoW2 itself has been done for a while, I'm still finalizing some parts of segsig, after which we will announce official testing (soon) and then launch.Latest info;
https://gulden.com/segsigthanks for the update. i was a bit disappointed by the delay of segwit. good to know that things are being finalized. i'll just assume that it will be done by the end of this month (as stated).
Gulden is doing SegSig, improved version of SegWit, according to the development page they getting a 58% saving , SegWit is only 25%.
oh yea thx for clarifying that. it's actually different.
GULDEN IS NOT COMING TO POLONIEX
Then the devs must live with Gulden never becoming a top 50 coin.
We will see in the future

Not only Gulden, as my per understand in recently Poloniex not have any plans about listed more altcoin to their exchange after May until today. I don't know the reason make them have this decided that but we will not see new altcoin listed Poloniex exchange in this year is possible.
Gulden is not any good investment at all. I dont know why these exchanges are thinking about listing this coin and if they are not, they have taken the wise decision. Gulden just like eth needs a lot of improvements. I dont think so any coin has enough potential for competing with bitcoins.
what exactly should be improved according to you? Gulden and ETH are not really comparable.
but yea obviously bitcoin is the most popular platform. Good thing you can use Gulden to directly pay in bitcoin
