Hoe later hoe beter...
Having Gulden listed on Cryptsy allows multipools that use Cryptsy's APIs to determine profitability to include Guldencoin in their mining schema. Essentially it would open the door to additional multipools at a time when we can't handle one. Cryptsy might be an option when an algo change is completed, but at this time it's just not needed. Additionally, most coins that go to Cryptsy are subject to bot auto-trading and pump and dump group activities. It's not a place for coins that value stability and longevity.
I hope the explanation doesn't get lost in translation
