Both SegWit1X and SegWit2X entail high transaction fees and determining their business models are an exercise in futility, although
Segwit Chains can still be used as a inefficient (Compared to BCC) institutional value transfer system.
All Segwit chains have altered so many fundamental properties of Bitcoin that it seems a stretch to refer to any of them by the Bitcoin name.
As of October 2017, two new forks are planned to occur on
the Segwit chain: SegwitGold is scheduled to split on or around October 25th, and the Segwit2x fork will happen at block number 494784, sometime in mid-November.
SegwitGold will be largely identical to
the Segwit chain, with the most notable changes being a change in the proof - of - work algorithm (meaning it will lose the vast network of computers that secure the Bitcoin network) and that the developers of the fork are granting themselves many free coins as a «reward» for their work on the project.
When capacity is restricted, fees rise dramatically (as we can see is the case with
Segwit chain), and Segwit Coin is no longer useful for many kinds of commerce.
Both the original Bitcoin and Bitcoin Cash adhere to this notion, while
the Segwit chain and the Segwit Core developers believe that capacity should be artificially limited, even if the demand to use the network is greater than the available capacity.
There would be a «
SegWit chain» and a «non-
SegWit chain.»
In practical terms, this means referring to the incumbent blockchain as
the SegWit chain.
Adding to the confusion there's the joint effort from two of the community's biggest news sites, Bitcoin.com and CoinGeek.com to promote Bitcoin cash (BCH) as The Real Bitcoin, and the «old» Bitcoin as «
The Segwit Chain».

Because the Bitcoin Cash fork was created by a minority group of miners, many services still regard the
Segwit -
chain as «Bitcoin,» although the two can be more accurately thought of as relatives sharing a common ancestor.
The
Segwit Core group remain adamantly opposed to any sort of native capacity increase, and have vowed to keep their own
chain (
Segwit1x) alive, although it is unclear if they will have enough miner support for the
chain to survive.
Segregated Witness (
SegWit), the update implemented to the BTC
chain on August 1, instead creates more space within the 1 MB block size by removing part of the signature data from each transaction.
Along with
SegWit, small block supporters also see off -
chain solutions like Lightning Network as key to scaling bitcoin.
Proposed by Bitcoin Core's developers,
SegWit's main goal is to send transactions off -
chain and onto second layers like the Lightning Network or sidechains, but it has already drawn a lot of criticism over its use of a 1:4 ratio, which some miners pointed out as a political decision that will bind bitcoin's trajectory for years regardless of technical factors.
SegWit's goal is to boost the blockchain's transaction capacity by sending transactions off -
chain and onto second layers like the Lightning Network, which is all about creating a global credit network that will tie up funds for at least half year, and really, how many people have six months available to place into a bank?

The main goal of
SegWit is to send transactions off -
chain and onto second layers like the Lightning Network or sidechains, which viaBTC said «are not equal to bitcoin's peer - to - peer on -

SegWit provides on -
chain scaling by separating the base transaction data from the signature data, which reduces the data transmitted in a transaction and in doing so allows higher concurrent transaction volume on the Bitcoin blockchain.

SegWit was not for the scaling features, but because it allows for instant payments off -

SegWit paved the way for solutions such as the Lightning Network, which creates a layer for bitcoin transactions to zip across the world without waiting in the main
