Meanwhile, Argo's (ARBK) revenue of £74.2M ($100.1M) in 2021 topped the average analyst estimate of $98.3M and surged from $25.6M in 2020, driven by an increase in its hashrate, the temporary drop on the Bitcoin (BTC-USD) network and higher BTC prices. 2021 mining margin of 84% vs. 41% in 2020. The increase was highlighted by bitcoin's (BTC-USD) upswing throughout last year. EBITDA of $71.4M
