The company said at the time it intends to use the proceeds for "general corporate purposes," including the acquisition of bitcoin and for working capital."As other players shift direction or decelerate growth, CleanSpark has doubled down on being the only remaining pure-play, public bitcoin miner," CleanSpark CEO Zach Bradford said in a statement.With the price of Bitcoin surging over $100,000 on Thursday, both MARA and CleanSpark's shares rose.Disclaimer: The Block is an independent media outlet that delivers news, research, and data.
