Antminer Z9 mini, hence the mini part. Will there be a full Z9 version? As the power consumption is only 300W for the mini version. What if there is a full Z9 version? Can Z9 mini uses other power supply as it only consume 300W.
Bitmain looks to be clearing out old chips stock. The z9 ad does not specify whether they are using 16nm tech.... but my bet is they are clearing out old chip wafers with several of these altcoin miners. The risk is that a competitor comes along and obsoletes the z9 with a significantly better performing miner. Just look at the x3 for a recent example...
