Hello, the reason for this decision was because of Bitmain's release of the Antminer Z9 mini (Equihash ASIC). BTG's vision has always been ASIC resistance so there was no discussion to be had about this, we had to act.

Our new algorithm is a collaborative effort, we are using a variant of Equihash that is quite a bit more memory hard (2.5GB per thread), this should be sufficient to invalidate this batch shipment.

Cheers.
