selling 250k metal

i have 250k met and need some rystal for my nanite. at standard rate 3:2:1 that is 166k crystal.
i can do it in a lot of small trades but i'd rather use my fleet slots for raiding so 1 big trade is perfered

Do you still need that crystal ?? i need some metal to make another nanite on a colony pm me in ingame if you need it
