According to Odaily Planet Daily, Vincent Maliepaard, marketing director of IntoTheBlock, disclosed data that Bitcoin miners' reserves have decreased by about 20,000 BTC since June. The Bitcoin halving two months ago may be a driving factor for the recent miners' sell-off, as profit margins have been declining since then. CJ Burnett, chief revenue officer of Compass Mining, said that large mining companies are still actively purchasing the latest generation of mining machines to improve mining machine efficiency, economies of scale, and gross profit margins.
