There is no specific tracker to monitor the packs amount sold out, but you may see how many CCD are sent to @ccceo.market in https://he.dtools.dev/@ccceo.market?symbol=CCD.
This way you'll have a snapshot of purchased CCDPACKs by counting amount of CCD tokens or better you join the discord channel to chat with mods. You can even ask a friend who is Silver 1 to get you packs at 50% discount.
RE: Last chance to get your hands on CCDPACK tokens – last month began! Now open: buy unlimited quantities*! (*=within the 999 limited edition, as long as stocks last)
