Bitcoin Cash trades on digital currency exchanges including Bitstamp, Coinbase, Gemini, Kraken, Bitfinex, and ShapeShift using the Bitcoin Cash name and the BCH ticker symbol for the cryptocurrency. On 26 March 2018, OKEx removed all Bitcoin Cash trading pairs except for BCH/BTC, BCH/ETH and BCH/USDT due to "inadequate liquidity". As of May 2018, daily transaction numbers for Bitcoin Cash are about one-tenth of those of bitcoin.
Bitcoin Cash (BCH) is hard fork (a community-activated update to the protocol or code) of Bitcoin that took effect on August 1st, 2017 that increased the block size to 8MB, to help the scale the underlying technology of Bitcoin.Nov 16th 2018: BCH was hard forked again and split into Bitcoin SV and Bitcoin ABC. Bitcoin ABC became the dominant chain and took over the BCH ticker as it had more hashpower and majority of the nodes in the network.
At the time of the software upgrade (also known as a fork) anyone owning bitcoin was also in possession of the same number of Bitcoin Cash units. The technical difference between Bitcoin Cash and Bitcoin is that Bitcoin Cash allows larger blocks in its blockchain than Bitcoin, which in theory allows it to process more transactions per second. Bitcoin Cash was the first of the Bitcoin forks, in which software-development teams modified the original Bitcoin computer code and released coins with “Bitcoin" in their names, with "the goal of creating money out of thin air." In relation to Bitcoin it is characterized variously as a spin-off, a strand, a product of a hard fork, an offshoot, a clone, a second version or an altcoin. On 1 August 2017 Bitcoin Cash began trading at about $240, while bitcoin traded at about $2,700.
Peer to peer (P2P) electronic cash is simply described as online money sent from one person to another without the need for a trusted third-party. As described in the original Bitcoin whitepaper by Satoshi Nakamoto, P2P cash makes use of digital signatures as part of the solution, but the main benefits are lost if a trusted third party is still required to prevent fraud. This makes P2P cash a trustless and safe way to transact without the need of intermediaries.
Both Bitcoin as well as Bitcoin Cash use a proof-of-work algorithm to timestamp every new block. The proof of work algorithm used is the same in both cases. It can be described as a partial inversion of a hash function. Additionally, both Bitcoin and Bitcoin Cash target a new block to be generated every ten minutes on average. The time needed to calculate a new block is influenced by a parameter called the mining difficulty. If the total amount of mining power increases, an increase of the mining difficulty can keep the block time roughly constant. Vice versa, if the mining power decreases, a decrease of the mining difficulty can keep the block time roughly constant.
EDA adjustments caused instabilities in mining difficulty of the Bitcoin Cash system, resulting in Bitcoin Cash being thousands of blocks ahead of Bitcoin. To address the problem with stability, a change of the Bitcoin Cash DAA was implemented and the EDA cancelled. The change took effect on 13 November 2017. After the change, the Bitcoin Cash DAA adjusts the mining difficulty after each block. To calculate the difficulty for a new block, the Bitcoin Cash DAA uses a moving window of last 144 blocks.
Rising fees on the bitcoin network contributed to a push by some in the community to create a hard fork to increase the blocksize. This push came to a head in July 2017 some members of the Bitcoin community including Roger Ver felt that adopting BIP 91 without increasing the block-size limit favored people who wanted to treat Bitcoin as a digital investment rather than as a transactional currency.This push by some to increase the block size met a resistance. Since its inception, Bitcoin users had maintained a common set of rules for the cryptocurrency. Eventually, a group of bitcoin activists, investors, entrepreneurs, developers and largely China based miners were unhappy with bitcoin's proposed SegWit improvement plans meant to increase capacity and pushed forward alternative plans for a split which created Bitcoin Cash. The proposed split included a plan to increase the number of transactions its ledger can process by increasing the block size limit to eight megabytes. Bitcoin cash is not one of the fastest cryptocurrency per transaction. And it is good investment for economic crisis.
