As others have said, no one knows for sure what is going to happen
Apart from likely a few very well connected (say, to Jihan and Ver) individuals, and I'm certainly not one of them. If you ask me (which seems to be the case), I'm inclined to think that there is more than we are told or allowed to see. We see that the total majority of miners (including Jihan Wu's Antminer) are kinda signaling their support for SegWit2x. At the same time, Jihan promised to come up with his own Bitcoin. Could he and his puppets withdraw their vote at the last minute and actually fork Bitcoin the hard way? I think they can, and what's most scary in all this, they might be accumulating hashing power right now (and might have been doing so for many months already) to release the kraken when the right time comes and quickly bring the opposing chains down to their knees. This is just one of the many scenarios which I don't think of as completely impossible
Anyone who comes with their own "Bitcoin" becomes discreditd in my opinion, like that mining company that said they would mine their own Bitcoin (an AltCoin). Nobody will fall on this trap of people trying to create new Bitcoins to destabilize what was built until now (I hope so). Everyone creating alternative Bitcoins will become AltCoin creators letting very clear which one is the original version, Bitcoin's renegades have no future.
In fact, you are farther from truth than you think
Since many people are involved in Bitcoin exclusively for profits (I don't mean it's bad, I'm just telling how things stand in reality), they don't particularly care which specific "brand" of Bitcoin allows them to earn profits. In this way, saying that nobody will fall in this trap is certainly not what is going to happen in real life provided Bitcoin does get forked, of course (which is not likely now when BIP148 seems to be close to failure). If this alternative Bitcoin shows decent profits, people will use it and no amount of determent or reproach will stop them
I believe it is economically not viable to fork bitcoin.
I remember in march hitbtc.com went ahead and featured BTU. I got my BTU, sold it faster than lightning to buy BTC (at irrelevant price, dumped it on the highest buy order). Now it is traded at 0.032 BTC / BTU, so it has a value of 3.2% of BTC and the daily volume is 1 BTC, basically downgraded to a p/d coin. You can still trade it and possibly make profit, but future = 0.
However, i don't trust big miners. This is the SMS i got from BTC and it is on their site too:
https://pool.btc.com/
115% earning protection comes!
From 11th July to 31st August,BTC Pool will guarantee your minimum earning not less than 115% by offering subsidies.
Why does it worth it for them (beside collecting hashpower to do "something"). I hate conspiracy theories but I must admit, there is something rotting with big miners.
