The closed testing is going well, that's literally all that can be said.
Testers aren't allowed to give inner details

But it's known that testers are people who knew and supported Gulden since 2014, so the testers probably are holding Gulden in their own wallets, which is super fine.
Since the testing started, the value of Gulden *increased* by 300% ! Do the math... the testers aren't afraid of their Gulden, there's much more BUY than SELL (they might be even buying even more, knowing that the update is awesome and going smoothly), so it's very easy and safe to say that the testing is going awesomely well
When it releases, the price will rise for sure in the following days/weeks after release, it's wise to buy before that happens.
Looks like they finally dropping SegSig from this release if testing is going well, it's good the devs acted quickly when they knew it wasn't going to be possible and changed course. PoW2 is what all the users are waiting for.
