I have no memory of anyone saying iota was finished prior to crowd sale.
Purpose of the crowdsale
Development. The crowdsale funds will be used for further development and finalization of the IOTA software as well as development of the Jinn hardware processor which will strengthen and help bootstrap the network in its growing phase. Additionally funds will be used on marketing efforts to help nurture the growth of the IOTA network and community.
Calm yo-self, sir!
