How much of our collective chip-manufacturing capacity is being devoted to Crypto mining? (a useless and environmentally destructive activity) Could Land Rover petition the UK Government to ban the exchange of Proof of Work coins in the UK in order to alleviate this chip shortage? Mining activity is a function of the price of the coin, and even bans from minor economies like Turkey have been enough to decrease prices.
