■ ARGO Blockchain is cashing in on soaring bitcoin prices.

The cryptocurrency miner’s production in November was 5pc higher than the previous month. This came despite a 9pc increase in network difficulty – a measure of how hard it is to mine a new block for the blockchain.

Argo made £4.2m of mining revenue in November – up a quarter on the month before.

It said the increase was driven by the rising value of bitcoin. Shares soared 19.3pc, or 1.7p, to 10.5p.
