Bitcoin Cash is pushed as the real Bitcoin by some in the community and many newbies will be fooled into it after they visit sites like bitcoin.com or r/btc. Beside that it can cause a lot of confusion that scares people away from cryptocurrencies and make them hesitant to buy any crypto. Bitcoin Cash is only created as an effort to control and is really bad for the reputation and adoption of crypto currencies (confusion, manipulation, hate, ect.) in general.
Scammers try to sell Bitcoin Cash as the real Bitcoin
Some try to sell Bitcoin Cash as the real Bitcoin to gain power and wealth for themselves, thus my advice to get your information from multiple sources before you invest! To avoid confusion between Bitcoin (BTC) and Bitcoin Cash (BCH), I will use the name Bcash from now and hope you will do it too! Here is a great article to explain why:
In technical sense Bcash is not Bitcoin
Bcash split off from Bitcoin at the 1st of August 2017 at the same time that Segwit got implemented in Bitcoin. Segwit had full consensus, so got implemented without any trouble and since a soft fork was used all old software is still compatible.
A hardfork is a change in the software that makes the old software incompatible. The purpose of a hardfork is a software update and it needs consensus to succeed. If consensus is not reached, a new minority chain is created that lives beside the original chain.
Bcash had by far no consensus, so their chain split off and took only a few percent of the miners with it. Original software was not compatible anymore, so really a new coin came into existence. Bcash is actually A FAILED UPGRADE OF BITCOIN.
Beside the bigger block size Bcash also implemented the so called EDA (Emergency Difficulty Adjustment). Because they knew they should only get a tiny part of the value and miners blocks would take extremely long to mine, so they implemented code to adjust the difficulty faster.
This caused hyperinflation (many new blocks per minute while normally one block per 10 minutes) followed by extremely slow blocks after the adjustment and this cycle repeated. The first code that the Bcash devs created ended up as a huge FLAW while the Bitcoin devs are maintaining the network smoothly for almost 10 years already! Later this flaw was taken out with another hardfork.
Bcash is NOT the true vision of Satoshi
Bcash supporters claim that Bcash is the true vision of Satoshi because payments were cheap when Satoshi was still around. Satoshi has never been clear about how to solve the scaling issue, so a debate came into existence.
When Satoshi launched Bitcoin it was really an experiment and nobody expected yet that it would succeed, let alone that it should become so big that it need to scale up so much. Saying that the way how BTC worked in the first years was the vision of its creator is like saying that internet is only made for email and video and social media are not the true vision of the creators of the internet.
Satoshi clearly said that he wanted the rest of the development to be done by participants of the open source project what works in a decentralized and permission less way before he disappeared. This means the vision of Satoshi is that hundreds of independent devs made his invention bigger and better than it already was and this is exactly what is happening with BTC now!
Bcash exist only through hate against Bitcoin and manipulation
Bcash supporters are never promoting their coin by telling how good it is, but always by talking negative about Bitcoin. Beside that every rise in price was caused by market manipulation exactly at a moment that Bitcoin showed some weakness.
Even the flawed EDA was used to steal miners from Bitcoin during one of the attacks. Two attacks took place where Bitcoin got spammed, wales dumped BTC for BCH and a huge (social) media attack with paid shills took place:
The Bcash price spiked 2 times in BTC terms and after that it fell back to the baseline. These spikes were clearly caused by manipulation, they took place exactly at the same time that Bitcoin got spammed and a lot of articles, tweets and posts came out that BCH is wonderful and BTC will die and is not working.
This means that this price is not based on true value, but purely on manipulation for self interest of some wales. As a medium of exchange Litecoin and Dash are way better because their block time is shorter and they are longer around and have a longer track record.
Bcash didn't implement segwit and the supporters of Bcash blocked the update to Segwit on BTC for around a year. This delayed all innovation that can be build on Bitcoin. Now since august 2017 we have Segwit and a lot of very innovative tech will roll out over the coming year (Lightning Network, RSK, Schnor signatures, MAST). Bcash will miss out on all of this and will turn out to be a useless coin (Like Bitcoin without innovation and slower than Litecoin).
Soon the tech of Bitcoin will greatly outperform Bcash and as soon as the market will see this the price will outperform too. Then it will become really expensive to pump Bcash and the value that came from manipulation will flow out. Investors advised by bitcoin.com and r/btc will lose money and they will miss out on the real Bitcoin thanks to a few scammers!
