There aren't many insiders I think, there's only a few developers, the guys from Nocks and Rijk. What can can happen is that PoW2 and/or SegSig is/are delayed and/or some features not possible. I think it's all panic selling, end of 2017 a lot of new people stepped in and thought they were on their way to get rich fast and now that the price was stable for a while around €0.20 they possibly step out while taking some profit and then the snowball effect kicks in.

I still see a good future for Gulden and now have a new chance to buy low again ;-)
