Honestly unless the price of bitcoin goes substantially higher in the near future. There will be no industrial sales at all.
Reason being is that a about a year ago. You could buy a $10,000 miner, get ROI after 5 months and make a few thousands afterwards with that miner. So for industry reasons buying 50-250 miners at a time was well worth it. Especially in many underdeveloped nations where electricity and labor was cheap.
Now miners are slightly little more efficient as before, but difficulty keeps increasing, and yet price fails to increase.
The same industries are not going to pay $1000 for a miner, which will get ROI after 5 months or so just to make a few hundred dollars profit per miner.
There is a big difference in, buying a $10,000 miner, and making $5,000 with that miner after a year or use THEN buying a $1,000 miner and making $500.
Buying 10 times as much miners isn't an option because it takes up more space and uses much more power and heat.
This is just my humble opinion. Who knows what the future will bring.
