Miners have sold more than $1 billion worth of Bitcoin this year, which appears to be a record number, said James Butterfill, director of research at CoinShares, Foresight News reported. However, this number is misleading because at the same time, miners are also producing record amounts of Bitcoin. Proportionally, miners have sold less Bitcoin as a percentage of total Bitcoin holdings, at 1% so far this year compared to 2% in 2018 and 2015.
