Gulden on the other hand is only being influenced by bitcoin price but not actual trading price. A lot of Guldens purchasing comes from direct Euro investment as seen on coinmarketcap (Nocks, litebit, guldentrader + 2 Euro exchanges due this year according to posts here) which will further keep things stable.
At least we have established Nocks is faking the volume as your Euro theory is not holding out. Gulden going down like a sack of shit like the rest of them.
On the other hand though, Gulden's market cap position increased, despite the price going down like the others.
