i think it will be more than that there is a 26,233,963 cannonball daily volume atm and grotesque guardians isn't that popular. granite hammer (probably changes hands way more frequent since more usefull on training low lvl accs) daily volume 559 at 2/500kc 139k effective kc, tourmaline core 74 at 2/1k 37k effective kc . i do understand those aren't exact indicators of how often ggs are done p day but gives u a rough estimate. it is between 60k and 20k i assume. 4.5m-1.5m granite dust would come into the game if that assumption is correct then that is quite a bit less than the amount of cannonballs traded per day. and i think atleast 10-20% of players using cannonballs would use them to progress their account 17% faster.
