it has always been about the money with everyone. some more than others. they want to maximize their profit. some by taking over the (bitcoin) project and be the center of it, some by creating a new altcoin (like the 100s of others) to make money, some by doing something so they can sell their products (that is right, companies like bitmain are going to sell so much more mining equipment now that there is an additional low difficulty thing to mine), ....
we can just hope that this greed and childishness doesn't cause any long term irreparable damage.
Honestly, I'm worried, and all the more because of the November fork.
If BCH continues to be more profitable to mine, and Antpool (and presumably other Bitmain pools) point more and more of their hash rate at it, that's going to disrupt the BTC network. Longer confirmation times, stuck transactions. More importantly, the network will be secured by increasingly less hash power.
And what are new investors going to think of all this? In a way, if you don't understand the intricacies of blockchains, it looks like Bitcoin can just be printed by forking the chain.
i don't think bitcoin cash can remain more profitable for long. there are multiple things that will ensure that.
1. the difficulty won't stay like this forever. it will be re-adjusted at some point and with the bigger hashrate the difficulty will increase and make the blocks harder to find and reduce the profitability.
2. there is always the issue with price. currently there has been about 980 blocks mined in the past 24 hours (it should have been 144 instead) that is all free new coins that are rewarded to miners. it is about 6.8x more than what it should have been (around 12,250 BCH) and it will continue to be this high until the difficulty is increased again.
we all know miners sell their coins for profit and to pay the bills. that is 6.8x more sell pressure on the market than normal.
