The 50-megawatt boost will allow Argo to run 15,000 more mining machines, taking its Bitcoin mining capacity to 1,360 petahash from 505 petahash, making it the world’s largest publicly listed crypto miner.

The agreement will be funded entirely from the proceeds of Argo’s crypto mining facilities in Quebec.

Mike Edwards, executive chairman of Argo, said the deal was a “major leap” for the firm, adding that the firm was aiming to be the world’s largest and most efficient crypto miner by 2020.
