Mining Bitcoin

Bitcoin mining is analogous to the mining of gold, but its digital form. The process involves specialized computers solving algorithmic equations or hash functions. These problems help miners to confirm blocks of transactions held within the network. Bitcoin mining provides a reward for miners by paying out in Bitcoin in turn the miners confirm transactions on the blockchain. Miners introduce new Bitcoin into the network and also secure the system with transaction confirmation.

People say bitcoin's security is backed by the hashing power of the miners, and if the miners are not incentivized then they will not mine to secure the chain. What if everyone has a miner that gives a little mining power to this chain in all of their appliances?

Bcash originally was on the path that s2x is on but responded to outrage by users and adopted a prudent approach and deployed actual replay protection.
Bitcoin Cash was a minority fork and thus felt responsible to implement the replay protection on its side.
From what it looks like SegWit2x is the majority chain (based on hashing power) and thus does not feel obligated.
Their 'opt-in' doesn't work because to make use of it requires replacing all existing software-- including signing code baked into hardware security modules
Would SegWit2x implement a strong replay protection they would have the same problem. (many wallets are still not working with Bitcoin Cash).
For a majority fork that would be like shooting in your own foot. Why would they want to do that?

There is no need to "attack" a minority chain. No one will care about it. It will have almost zero hash power, will take months to propagate a single block and will die out when no one supports it.
You do realize what happens when you fork a chain and dump it at current diff onto 5% or so of the hash power, right?
How about them 5 hour blocks with max diff drop at current? Yeah. That chain won't recover. Ever. This isn't Ethereum classic, where a few GPU miners can keep pushing the chain.
This is Bitcoin. When 90% of hash power fork it, the minority chain is irreparably screwed. Unless you plan on investing $200 million in ASIC over the weekend.

Centralization in crypto refers to what degree hash power is owned by a single entity, or even how centralized it is geographically.
Authority is the issue of a group or person exerting influence on the network.
Before Ethereum moves to POS, in which case a highly centralized ownership of tokens could become an actual issue, Ethereum is less centralized than Bitcoin THOUGH more Authoritarian I would agree.
Bitcoin is by far the most centralized crypto of all already, so if that scares you it's a bad choice.

Blockchain Basics Explained - Hashes with Mining and Merkle trees What is hash rate in Bitcoin ? What Is A Bitcoin Hash? Cryptocurrencies and Digital Currency  Crypto Cousins What is a Bitcoin hash and SHA-256

A hash algorithm takes data of any arbitrary size (numbers, alphabets, media files) and transforms it into a fixed alphanumeric string. The fixed bit size can vary (like 64-bit or 128-bit or 256-bit) depending on what hash function is being used.. And this fixed size output is what is called a hash.In other words, a hash is the cryptographic byproduct of a hash algorithm. A hash algorithm turns an arbitrarily-large amount of data into a fixed-length hash. The same hash will always result from the same data, but modifying the data by even one bit will completely change the hash. Like all computer data, hashes are large numbers, and are usually written as hexadecimal. Bitcoin transaction hash in wallet . Transaction hash (txid) is an identifier used to uniquely identify a particular transaction. All on-chain transactions (the transactions from or to external addresses) have a unique txid that can be seen in transaction details. A transaction hash usually looks like a random set of letters and numbers. Hash functions in bitcoin. In the bitcoin protocol, hash functions are part of the block hashing algorithm which is used to write new transactions into the blockchain through the mining process. OK, but what does hashing actually mean? Underneath the hood, Bitcoin mining is a bit like playing the lottery. Roughly every 10 minutes the Bitcoin code creates a ‘target’ number that the mining machines try to guess.
