## **5. Key precautions**
1. * * Electricity supply**
-Ensure stable electricity supply of * * 150 kW * *, preferably by signing long-term low price contracts (such as industrial electricity prices).   
-Avoid areas with unstable power grids, otherwise mining machines are prone to damage.   

2. * * Thermal management**
-When mining machines are running intensively, the temperature is extremely high, requiring forced ventilation or water cooling systems.   
-High temperature environments (>30 ° C) can reduce the lifespan of mining machines.   

3. * * Policy Compliance**
-Choose mining friendly regions such as Texas in the United States and Quebec in Canada.   
-Avoid illegal use of electricity or undeclared mining operations.   

4. * * Risk Management**
-The price of Bitcoin fluctuates greatly, and 3-6 months of operating funds need to be reserved.   
-Hedging (such as futures contracts) can be considered to reduce the risk of currency price decline.
