Bitcoin (BTC) and altcoin miners who fled China's cryptocurrency ban to neighboring Kazakhstan have been hit by a new setback - the authorities are forced to limit mining companies' energy use. This probably means that the mining industry will be concentrated even more in the United States. As the cold winter months approach, the alarm bells have started ringing, and the Ministry of Energy in Kazakhstan announces that disruptions have occurred at three of the country's largest power plants. The ministry has acted to create a bill that "would limit the total capacity of [crypto] mining installations operating in Kazakhstan to a maximum of 100 MW." The news will hit industrial miners the hardest of all. If adopted, the bill will also limit production at individual centers. A special tax rate for crypto miners will also be introduced according to the ministry: Miners would be told to pay an additional $ 0.0024 per kilowatt of energy consumed. Crypto mining is a large business and a huge growth area in Kazakhstan, which according to University of Cambridge figures from August 2021 now accounts for 18.1% of the global average monthly bitcoin hash rate.
