I wonder if it is what I understand.

Right now, major miners, including JihanWoo, are not mining BTC and concentrating all their hash power on the BCH. So, the BTC network is currently suffering from normal transsactoin, and the BCH is continuing to be pumped. right?

By the way, is the mining things going to increase 'profit rate' if there are fewer competitors? Then, if the competitor is small in BTC like now, is "the other miners" get a much bigger profit when they mined BTC now?

Or until the difficulty is adjusted up to two weeks, "other miners" do not get that benefit for up to two weeks? When major miners return in two weeks time, are they also getting more BTC because of the lower difficulty?
