Moron, if they only mine BCH and sell it for profit it would crash the price even further. Do you actually think mining with a high hashrate is beneficial? Only when 51% threat exists.
More miners mining BCH and selling means more liquidity which is better for BCH. Obviously miners don’t all always sell (I don’t). Happy to get angry replies!
Bitmain specifically holds and burns some BCH to keep the price more stable, if they only mined BCH they would have to sell more of it for profit. Why don't you understand this?
