Cryptocurrency mining is perfectly legal in Europe and only subject to standard electricity rules, according to an EU commissioner.
In a statement released last week, Mariya Gabriel, European Commissioner for Digital Economy and Society, addressed concerns about the power-intensive nature of cryptocurrency mining, while clarifying the regulatory status of the industry.
Gabriel said:
"If the energy consumed for this activity is produced according to law, there is no legal basis to forbid or even limit it. ... As mining of cryptocurrency is not an illegal activity, the Commission did not put in place any means to track it, so far."
