Let me try to explain the economics behind mining. Basically, whoever has the most money is the most powerful. With btc blocks being only 1mb, virtually anyone can afford the proper equipment and join a mining pool. When block sizes increase like is happening with BCH to 32mb and then larger in the future, the equipment used to mine the 1mb block is fast enough to mine the bigger blocks. New specialized ASICS will be created to mine the bigger blocks meaning more capital. Bitmain is the largest ASICS producer/retailer in the world owned by Jihwan Wu and Roger Ver who are the leaders of BCH. As you can see, they are highly motivated to see BCH overtake BTC and you can now understand the passion stemming from both sides of the equation.
