would there is a price drop accordingly
I am looking into the possibility for using chip discounts for this group buy.
Yes. Actually, people that have chip credits can show their interest here and if it looks like we can fill at least 100 chips I will re-write the group buy to take into account chip credits, and also publish info on credit transfer with payment info.
That way this group buy would use chip credit orders only, and the price will reflect this ASAP.
