Well... Seriously? Exactly 90,169? What is the point to do that? :P It will be probably the hardest one to achieve :D
It is exact sum raised by crowfunding so that is quite a point.
Drwarf merchant who grabs si's and makes to dwarftown can achieve it in under twenty minutes [might need some buy/sell rocks to rounding so grab these too] real time since that is not amount of total balance it is total paid to shop. Does not even come close to steel/titanium man.
