If I'm not mistakin, DUSK is only conducting a private sale but yes, with the current market slump, I think it will have an effect as every investors are now becoming more cautious and in a "wait and see" attitude towards investing in crypto.
It will also have an effect to previous investors and funding, looking at how many of the ICO not reaching there soft-cap and the sudden swing of bitcoin price many project will fail, but dusk is not like any other ICO so it might be another story with them.
