While the bitcoin community is celebrating segwit activation and the recent price rally, the segwit2x agreement date is coming closer.
We know that the 2mb (8mb) hardfork is controversial and not supported by the core developers https://en.bitcoin.it/wiki/Segwit_support
But segwit2x announced they plan to hardfork a bigger block in November https://segwit2x.github.io/segwit2x-announce.html
I am seeing the possible scenarios:
1. Bitcoin forks a third chain Bitcoin Segwit2x.
2. Bitcoin hardforks to Segwit2x without creating a chain split.
3. Bitcoin Cash implements segwit via softfork before the segwit2x hardfork and claims they already are segwit2x and there wont be a hardfork at all.
4. Segwit2x supporters fork Segwit2x from Bitcoin Cash to not directly affect bitcoin with this controversial hardfork.
On Scenario 3 and 4 I would expect a pump for bitcoin cash , but really hard to guess the probability of it.
Scenario 3 or 4 would be very interesting.
Signature data is not removed from the blockchain its inculded in the witness data of each block and can be downloaded and verified by every segwit ready node.
segwit2x was cancled but its likely that somebody else will run the code anyway but it wont have much support.
And its also still possible that someone forks a segwit version from bch claiming to be segwit2x as well (just to pump bch).
