My main concern is with future discussion about the "early sale (20%)".
How do we know any funds were actually raised? Since you say factom will provide no proof of presale funds raised, this will forever be a possible developer 20% hidden premine scam.
I believe there was funds raised but without proof of these raised funds, there will always be this negative theory that you are scammers. Maybe you faked a presale. Maybe you plan to give away some of the early sale (20%) factoids for precrowdsale marketing.
You should show the same transparency with presale as you will with crowdsale. It would be the "Honest Record-Keeping" thing to do.
Amen, fartbags!!!! We've seen this MO far too many times around here and the lack of transparency will come back to haunt you, many of us will ensure that.
Do the right thing.
