How does bitmain control over 50% of Bitcoin cash? https://cash.coin.dance/blocks/today https://cash.coin.dance/blocks/today Doesn't look like any pool is dominating unless Bitmain controls many smaller pools. However, I'd argue that any domination is a side effect of Bitmain being the 1000pound gorilla in BTC to start with. THeir BTC pool is at 20%. (there are a LOT of people unhappy with Bitmain's business practices). I mean there is no cost effective hash/kw alternative to Bitmain S9s. The scary thing is that my friends and colleagues are buying S9s because no real alternative exists if you want to mine BTC(and I suppose Bitcoin Cash too)
