At certain points of their operations they do sell some Btc for business operations but I believe they will soon be a net adder of Btc like past quarters and they don’t sell Btc every quarter. They are in an expansion phase of their sites as I wrote in the post and their goal is to stack / hold as much Btc as possible and use fiat to expand. Also they mine Btc at a lower avg cost than we can buy it at market prices
