The primary question posed by the cryptocurrency community is "Is bitcoin mining legal?" The answer varies by country. In the United States, mining operations must register with the government and obtain permits before starting their operations. In Paraguay, mining operations must obtain industrial electricity authorization. However, the Senate has yet to pass a similar bill.
Bitcoin mining is technically legal in most countries, but governments may still prohibit the practice. Some countries, such as Cuba and North Korea, have very restrictive financial laws. Other governments may be less concerned with mining than others, and may even look favorably upon it. Some countries are even actively seeking to prevent its development, arguing that it could lead to revenue from taxes.
