The foundation of bitcoin was built in peoples home spread across the globe.
Mining is no longer feasible at home anymore, by limiting this technology to data centres it centralises bitcoin to farms

If bitcoin is to succeed than the foundation must remain with the people, mining machines must be created to allow people to mine in their own homes.
There is nothing decentralised about a currency mined and managed by huge data centres.

I arge all suppliers of mining machines to create machines that ROI for home use (i.e air conditioned, low noise, competitive hush and affordability)
There is a huge untapped market here which would help the stability and success of bitcoin.
