Bitcoin Cash is a cryptocurrency.[4] In mid-2017, a group of developers wanting to increase bitcoin block size limit prepared a code change. The change, called a hard fork, took effect on August 1, 2017. As a result, the bitcoin ledger called the blockchain and the cryptocurrency split in two.[5] At the time of the fork anyone owning bitcoin was also in possession of the same number of Bitcoin Cash units.[5]

Classification

Bitcoin Cash is a cryptocurrency.[6] In relation to bitcoin it is characterized variously as a spin-off,[6] a strand,[7] a product of a hard fork,[8] an offshoot,[9] a clone,[10] or an altcoin.[11]

History

In 2016, bitcoin's block size limit has created a bottleneck resulting in increasing transaction fees and delayed processing of transactions that cannot be fit into a block.[12] This situation contributed to a push by some in the community to create a hard fork to increase the blocksize.[13]

Until July 2017, Bitcoin users maintained a common set of rules for the cryptocurrency.[14]

In July 2017, the Bitcoin Cash name was proposed by Chinese mining pool ViaBTC. Some people also use the name Bcash.[15]

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 and devised a plan to increase the number of transactions its ledger can process by increasing the block size limit to eight megabytes.[14][16]

A small group of mostly China-based bitcoin miners were unhappy with bitcoins improvements meant to increase capacity and pushed forward the split which created Bitcoin Cash.[10]

The protocol with an expanded block size limit was first described by hardware manufacturer Bitmain in June 2017 as a "contingency plan" should the Bitcoin community decide to fork; the first implementation of the software was proposed under the name Bitcoin ABC at a conference that month.

When BitCoin Cash launched in early August, BitCoin holders received one Bitcoin Cash token for each Bitcoin they held.[13]

By November 2017 the value of BitCoin Cash, which had been as high as $900, had fallen to around $300, much of that due to people who had originally held BitCoin selling off the BitCoin Cash they received at the hard fork.[13]

Trading volumes for bitcoin cash are about one-tenth of those of bitcoin.[6]

Exchanges

Bitcoin cash trades on digital currency exchanges including Bitstamp,[17] Coinbase,[18] Gemini,[19] Kraken,[20] and ShapeShift using the Bitcoin Cash name and the BCH ticker symbol for the cryptocurrency. A few other exchanges use the BCC ticker symbol, though BCC is commonly used for Bitconnect.

On 26 March 2018, OKEX removed all Bitcoin Cash trading pairs except for BCH/BTC, BCH/ETH and BCH/USDT due to "inadequate liquidity".[6]
