Twitter and Square CEO Jack Dorsey posted on Tuesday that he is trying to mine Bitcoin. In response to another user's tweet about Bitcoin mining, Dorsey wrote, "I am also trying to mine with Compass Mining." He did not elaborate. Compass Mining is a service that provides custody, supply, and operation of cryptocurrency mining platforms for "miners" who do not want to purchase and maintain mining equipment on their own. The starting price for purchasing mining hardware from Compass mining is $8,200. According to data from the company's website, historically, Compass miners have made approximately $33 a day in profit. Bitcoin investors can begin to understand this process directly through mining, rather than just buying digital currency. For Dorsey, this is not surprising, as he has supported Bitcoin personally and professionally many times in the past. In July of this year, at the "B-Word" conference hosted by the Crypto Council for Innovation, Dorsey reiterated his enthusiasm for Bitcoin and expressed the hope that it would bring world peace. At the 2021 Bitcoin Conference in June this year, Dorsey explained that he believes Bitcoin can prevent currency devaluation and speed up cross-border fund transfers.
