The machines used in bitcoin mining run on electricity, the very electricity is currently halting mining in the US, and mining industry is moving out.

EXPENSIVE ELECTRICITY

Electricity is comparatively expensive in the US. The cost of electricity consumed to mine one bitcoin is much higher than the value of the bitcoin itself, so bitcoin companies are waiting for a bull market to turn a profit, and this creates uncertainty.

SHORT POWER SUPPLY

The setting up of new power plants is not keeping pace with local demand. Even mining industry workers are not able to oppose it because their house also has the same problem. Therefore, electricity for mining is available only in the winter and summer.

WORLD CALLING 

No mining company has been called directly, but governments in other countries are making attractive policies that can benefit the mining industries. Such as cheap electricity (Lebanon), tax exemption (El Salvador), environment-friendly mining (Bhutan), etc. This is causing the departure of American companies.
