Instead of physically transporting the coal, it’s easier and more cost-effective to establish a Bitcoin mining operation near a source of coal and convert carbon directly to crypto. #Bitcoin enables Chinese entrepreneurs to export coal by burning it and using the energy to mine. — Emin Gün Sirer (@el33th4xor) July 20, 2015.
