At this point I am working under the assumption (and I hope I am wrong) that the 2 MB hard fork of the SegWit2X NYA will not happen and the Chinese mining cartel is not really upset because they are planning on using Bitcoin Cash to take over control of Bitcoin. I would be interested in hearing from those who think this poker game will end with Core the winner and why. There is a lot of money at stake here.

Bitcoin Cash can not become the dominate chain since its future is more risky than
sticking with the current chain. It is fine to throw a little bit of hash on the Bcash chain
and get some coins and hold for unexpected profit in the future, but if miners move
majority of their hash to that chain, thus directly harming the Bitcoin chain, they will
have placed their future in the hands of Bcash, which will be regulated by the Chinese
Government and its Intelligence services. Bcash is not about freedom or bigger blocks,
it is about steering the network in a way in which it becomes capturable and thus
compliant to regulation directly within the protocol. It will be enforced by government
approved, licensed, and controlled miners.


...

Miners are essentially squatters. If they get up and move, they will lose their place.
So the first miners to fully move over to Bcash are the first losers in the larger game.
That is why some are just dipping their toes, it's because no one really wants to swim.
Evidence??

What place would that be?

What with this anti-chinese miners posting that's been going on for too long?

1) Majority of all large companies and industries that are Chinese are internally
controlled/steered by their government. This is not only done for the purpose
of manipulation of markets, preventing competition, and other aspects within
their society, but also for military/intelligence strategic purposes.

In the west, it is known (and unknown) that many western companies may
work with their governments secretly or have divisions within them where
there are government employees stationed for expedition of certain national
security interests, but that is very different than with China. In the west, it
could be contested or denied, you are not forced to work with or for the
government (unless in war time), since corporations are separate entities by
design, but in China they are not really separate and can not be contested. If
you do not comply, you are shut down and then taken away from you and
given to a government proxy. Almost all major companies/industries are
actually owned and controlled by the Chinese government.

So, the evidence needed to prove this could happen with Bitcoin is not needed
within a press release where they publicly announce to the world that they will
do this, because it is already common practice in China with large corps. Their
miners will be forced to be licensed and approved by their government. That
license will be contingent that they comply with governmental directives. If the
government wants them to restrict certain UTXOs, or maybe roll back work, it
could be possible to do so. When this occurs, those Chinese miners are forced to
do it to "keep their jobs and money" or "stay in business" and not be thrown in
jail. It is not a malicious miner attack to destroy the network for them, it is a
roll back attack so that they get to keep their jobs and money from their
government taking it all away from them. That is a realistic concern that
must be weighted into the future and future possible actions as likely to occur.
If it never does, well then great, but to deny it until there is a press release will
mean we will be reactionary when it occurs. It is conceivable and likely now.

2) The place I am talking about is their position within the block competition race.
If they move majority of their hash to BCH and leave BTC, they are taking a major
risk. It is one thing to do this with altcoin mining, where ultimately they convert
those coins into BTC, but to risk that with BTC itself, is too crazy for me to believe.
Maybe I will be wrong, maybe miners are truly 100% dumb greed and not 100%
smart greed, but we'll see what occurs in a short amount of time now.

3) I have no problem with the Chinese people or the Chinese Miner operators,
in general. When I say, the "Chinese Miners" what I'm really meaning is the large
amount of hash that is located within one country, that is under the control of a
government who is not friendly toward what the cypherpunk or western human rights
ideals are. It is not directed toward the race of people, it is directed toward their
government, when I say it, and IMO I think that is what most people mean when
they say the "Chinese miners". If someone is a miner who is also Chinese, but lives
outside of China and is mining in Europe or wherever, I don't include that miner
within my term of "Chinese Miners". Maybe people should say "People's Republic
of China Miners" (PRoC Miners) to be more specific?
To me, Chinese Miners = PRoC Miners.


Edit: To add to my third statement, today there is some info circulating that
the Russian Government is going to get involved in mining bitcoins, and that they
supposedly want to compete against the Chinese Miners. That is fine in theory,
but my concerns about the "PRoC Miners" I stated above will also be applied to
this "Russian Miners" possibility.

Interestingly, if this is serious and takes off, it may mark the start of a new era
of Bitcoin mining, where individual countries will need to mine the Bitcoin chain
themselves, with public governmental authority and tax money backing, to ensure
that their countries and their citizens txs are not restricted or denied by other
countries, especially for scenarios where one day Oil is denominated and paid
only by BTC. They will be forced to secure the Bitcoin chain, so that they are
not denied of or extorted, for resources or trade on-chain later in the future.
Fun possibilities indeed.

How can Bitcoin Core prevent miners from switching en masse to mining the Bitcoin Cash chain?

They can release better software, which will reinforce confidence in Bitcoin, cause it's price to rise and make miners switch back to it, as it will be more profitable to mine Bitcoin instead of Bcash.
And Bitcoin hodlers can help this process by dumping their Bcash, causing it's price to crash and making miners to switch back to Bitcoin.

You realize Bitcoin Cash will be more profitable to mine soon even with a lower price?

If you think Jihan will mine another altcoin youre are wrong. Bitmain needs a certain price fix for his expenses otherwise Jihan goes bankrupt.

Bitmain is not a 1 man company, you cannot run a succesfull business if you cannot fund it  Undecided

Not sure you understand what "more profitable" means. Also, if enough miners switch to Bitcoin Cash then BitcoinSegwit will be the alt coin.

After the hard fork on Aug 1, 2017 both Bitcoin and Bitcoin Cash had the same difficulty. Due to the EDA built in to the Bitcoin ABC client difficulty on the Bitcoin Cash chain quickly ramped down to 144323701657.02 or 17% of Bitcoin current difficulty. The value will be even less when Bitcoin difficulty adjusts up in a few days. Once difficulty on the Bitcoin Cash chain drops to less than 8% of Bitcoin difficulty miners will be incentivized to switch mining to the Bitcoin Cash chain. How can Bitcoin Core prevent miners from switching en masse to mining the Bitcoin Cash chain?

Miners follow price. That means, hashrate will follow the higher price, and the higher price will always be the real Bitcoin, not XT, not Classic, not Unlimited, not segwit2x, not ABC/Cash... and the list goes no and on.

The price will always be higher on the real legacy chain, because the big whales will never support the forks.

Miners that support other chains will find themselves in bankruptcy soon enough to realize their mistake and get forced to go back into the legacy chain.

It looks like the Chinese are dumping money into Bitcoin, not Bitcoin Cash.  I would think that if the Chinese Govt really really wanted to kill bitcoin they would just keep buying all the BCC until BCC market cap was like 50B usd.

I was not asking for evidence, just some articles explaining the theory that Chinese Govt is behind BCC.  I thought Craig Wright was pushing BCC more than anyone??  I also thought that the Chinese were Anti-BigBlocks?

Thanks for all the input.

How can Bitcoin Core prevent miners from switching en masse to mining the Bitcoin Cash chain?

Ah, very simply.

It's not the longest chain that wins fork resolution, it's actually the chain with most hashes.


And reducing the difficulty by 92% will result in the ABC chain having fewer hashes, and the resulting lower security. Bitcoin miners could use their mining equipment to play havoc with the ABC chain, if they chose to do so.

The ABC chain will be inherently insecure against attacks, until it's hashrate and commensurate difficulty reaches that of Bitcoin's. And they'll need to convince a huge majority of miners to switch to catch up, it will be much more than 50%.

And they still need to convince the users, even after all that electricity and arm-twisting. If someone can pwn the Bitcoin Network that way, get ready for the PoW change 21st Century CPU mining goldrush, bitches Grin Grin Grin

I am confused. Why should they? This is a free market. Miners can go whereever they want to. Its none of their business where miners uses their resources for. If you want a dictatorship, why not go to North Korea.

Bitcoin Core doesn't have to do anything, and they shouldn't do anything, there are a lot of SHA256 coins out there, if they are more profitable to mine, miners go with it until it is not profitable anymore and so on.

Mining is a free market, people go with what's more profitable at the moment.

What place would that be?
If I understand correctly, he's implying that by leaving the earlier chain they are making it more profitable to mine on the earlier chain and that someone else would fill the gap.  Once that happens, moving back would be an economic burden on the miners.
What with this anti-chinese miners posting that's been going on for too long?
I don't know and it's very annoying.  Also, if the price rose on Bitcoin Cash, non-Chinese miners would start mining on that chain as well.  So not only is Chinese miners being on the Bitcoin Cash chain not a problem, it wouldn't actually happen.
@AgentofCoin; @squatter good points well reasoned thank you.
How does difficulty adjust downwards in abc bitcoin if its hashrate is too high and over how long a period?
We're finding that out right now.  You can check what Bitcoin Cash's mining profitability has been doing relative to Bitcoin here.

Evidence? no lol this is a war not a science convention.
It's logical to deduce that statist govts attack bitcoin.
Bitcoin cash is an attack on bitcoin.
The Chinese govt is one of the least inept.
China was uniquely positioned to churn out asic miners more efficiently than other states.

The miners who are not based in China, but will be taking such a risk, is a gamble
that no sane person/miner would take. So IMO, majority of the miners will not leave
the Bitcoin chain for the Bcash chain as you think could happen. Through there may
be times where it is more profitable to do so, it must be weighted against whether the
long term viability is realistic.

Why would you let your reliable golden goose bleed out and potentially die, just to get
a few more eggs from a unknown neighbor goose, owned and controlled by an unknown
farmer? Most smart farmers stick to and protect their own geese. You never know if that
unknown neighbor goose is diseased or etc. or what risks you are actually taking on.

So, IMO there is a higher chance of SegWit2x becoming the new chain, then majority
of Bitcoin miners actually moving over to the Bcash chain (though I think there is also
a higher chance that the 2x aspect does not occur). The risks of moving over to Bcash,
or moving back and forth between the chains, is so massive, its insane to accept as
something that could realistically happen, IMO. It involves blind faith, which miners
in the past haven't been very interested in (unless its a purposeful attack type).

Miners are essentially squatters. If they get up and move, they will lose their place.
So the first miners to fully move over to Bcash are the first losers in the larger game.

Agreed. And if miners are forced to attack we can change algo.

What is the reverse of this problem?

How does difficulty adjust downwards in abc bitcoin if its hashrate is too high and over how long a period?
I suppose they can fork in an adjustment pattern that way to suit their needs?

There is nothing Core can or should do. The reality is this: any group (developers, users, services, miners) can defect from the consensus and create a hard fork at any time. Changing the parameters of difficulty readjustment is their prerogative.

Miners are unlikely to switch to Bitcoin Cash en masse even if it is more profitable to mine, because it is pretty well understood by now that encouraging such a major network split will destroy the value of both networks. Miners are rational; some may defect, but most will remain.
