1. Introction: bitcoin cash is a branch of bitcoin. In order to solve the problem of long transaction time of bitcoin, at 20:20 on August 1, 2017, a small number of mining machines began to use 8m block to start mining, and the transaction confirmation speed was thousands of times faster than that of bitcoin using 1m block< Br > release time: bitcoin cash is a hard fork of bitcoin on August 1, 2017< < br > maximum supply: 21000000bch < br > current total circulation: 16959625bch < br > market volume: currently accounting for 5% of the cryptocurrency market < br > market value: $21882632910 < br > Future Prospects: bitcoin cash (BCH) is a cryptocurrency representing large blocks, which was born in August 2017. Bitcoin cash (BCH) focuses more on chain trading. Therefore, compared with bitcoin core, bitcoin cash (BCH) has the advantages of low handling charge, no congestion and irreversible transaction.
2. Bitcoin cash transaction is not congested, and the handling charge is lower
3. Compared with bitcoin, the biggest advantage of bitcoin cash (BCH) in payment is that the network is not congested, transaction fees are low, and zero confirmation payment is supported
bitcoin cash is the proct of the competition for bitcoin expansion. It is a large block version of bitcoin. At present, it has been expanded to 32m. In the short term, it is impossible to have the problem of network congestion, and bitcoin cash will continue to expand according to the market demand
bitcoin is still locked in 1m block size, which leads to the congestion of bitcoin network, and the number of unprocessed transactions is amazing. Isolation verification and lightning network have not solved the problem of bitcoin network congestion.

4. Bitcoin (BTC) is the most popular digital currency in the world. The spread occurred on August 1, 2017. In a "hard fork" event, a new digital currency called bitcoin cash (BCH) was born. Due to version switching, bitcoin blockchain is forked into two independent blockchains. Everyone who owns bitcoin before the fork is entitled to the same amount of "bitcoin cash" tokens, similar to a dividend in a stock
bitcoin cash (BCH) is a new version of bitcoin with different configurations launched by a small number of bitcoin developers. It is a new type of blockchain asset. On August 1, 2017, the mining of bitcoin cash will begin, and each bitcoin investor will have the same amount of bitcoin cash (BCH) in his account
(1) the transmission mode of the two is the same
bitcoin cash and bitcoin are completely decentralized, and the central bank does not issue or need a third party to operate, but the electronic cash is transmitted through the Internet
the previous life of bitcoin cash is bitcoin. Before the bifurcation, the data stored in the blockchain and the running software are compatible with all bitcoin nodes. After the bifurcation, it has little association with bitcoin and becomes a new currency
(2) the block capacity of recording transaction information is different
the block capacity of bitcoin is 1MB, while the segwit of bitcoin cash is deleted, which cancels the limit of 1m block size, supports 8m block size at most, and adheres to the on chain expansion route. It is a blockchain asset generated by bitcoin ABC scheme, which has greater stability and security. It can also support more transactions in a specific time. The size of the first BCH block g up by bitcoin cash has exceeded 1MB
(3) the difficulty of the two algorithms is different
there are 21 million bitcoins at most. With more and more bitcoins being g and less and less remaining, the difficulty of the algorithm becomes more and more difficult. Bitcoin cash adopts the dynamic difficulty adjustment mode, and the proction difficulty will be adjusted with the computing power in the whole bitcoin cash network. The more nodes you join, the higher the difficulty, otherwise, the lower the difficulty. Because bitcoin cash takes a long time to get out of the block, bitcoin cash began to adjust the difficulty of mining on August 8, and improved the speed of getting out of the block
technically, both bitcoin cash and bitcoin's workload proof algorithms are sha256, but the difference is the difficulty adjustment mechanism. The measures taken in the original bitcoin chain are to adjust the mining difficulty once every 2106 blocks are excavated according to the computing power. In order to prevent the situation of insufficient computing power, bitcoin cash adopts the emergency difficulty adjustment mechanism (EDA), which automatically reces the difficulty by 25% if the number of blocks is less than 6 in the last 12 hours
from the point of calculation power allocation: when BTC and BCH use sha256 algorithm together, miners can decide which kind of mine to dig according to the mining income. In the past three months, whenever the difficulty of BCH is reced and the mining income is greater than BTC, the computing power will flow into the BCH chain, which seriously affects the block speed of the two chains
problems faced by bitcoin cash
BCH has been controversial since its birth. The dispute between BCH and BTC, and the contradiction between miners and core may continue. This is caused by the defects in the design at that time. It is a "congenital disease" and the irreconcilable contradiction after birth, which leads to today's inseparable situation. And with the rising price of BCH, this contradiction may be further intensified.

The reason why the programmer threw away 7500 bitcoins as garbage is because these bitcoins are stored in the hard disk, and he carelessly threw away the hard disk
recently, a British programmer found that in 2013, he accidentally threw away the hard disk with 7500 bitcoin private keys as garbage
these 7500 bitcoins were g up by him on his personal computer. In order to retrieve the hard disk, he went to the landfill, but even if he "wanted to go back to the past", it was impossible to recover it. 7500 pieces, estimated at the current price of 32000 dollars, which is equivalent to throwing 240 million dollars into the garbage can
In fact, millions of bitcoins have been "lost" worldwide. But the "lost" bitcoin did not disappear. On the blockchain, you will record how many bitcoins you have in your name, but you need a private key to tradethe programmer is careless, that is, after throwing away the hard disk, he adds symbols to the string of very complex letters. Nowadays, the "value" of bitcoin has risen sharply. Those who lost bitcoin will naturally regret it
{rrrrrrr}
extended data
reasons for bitcoin's recent surge:
according to the analysis of CICC's research report, bitcoin's price rose nearly three times from $7200 at the end of 2019 to $27084 (as of December 28, 2020), and became the asset category with the highest increase since the beginning of the year, Even more than the faamng tech giants index
in addition to the impact of global liquidity easing, the analysis shows that the financial innovation of financial institutions represented by PayPal, Robinhood and grayscale in broadening the channels of digital assets in the past year is the structural reason behind the nearly three times rise of currency price in the past year. In the short run, the price of bitcoin may fluctuate greatly, driven by liquidity and the inflow and outflow of speculative funds. However, in the long run, the continuous expansion of the traditional investor base is concive to the stable rise of the price of bitcoin and other digital assets
6. It's mainly about interests. There are mainly the following types of people who oppose BCH:
1. They hype themselves and pave the way for their bifurcating bitcoin. For example, Liao Xiang, who once strongly opposed big blocks, paid big money, and they all bifurcated bitcoin
2. Misled by the core development team, the melon eaters regard the miners as a group of criminals
3. The core development group's opposition to BCH is not only a divergence of development roadmap, but also a dispute of interests. The lightning network promoted by the core development group can make the gold owners behind it profit through the lightning network.

7. Personal opinions are worth investing in
the total number of BCCs, like bitcoin, is 21 million. It inherits almost all the user groups of bitcoin
BCC is calling for the birth of the golden key. As soon as it is born, its price exceeds that of Ethereum, and its market value ranks in the top three
BCC has strong community support, which was once the supporter of bitcoin block
most of the global digital currency trading platforms and wallet service providers have chosen to support it.

8. Bitcoin cash is a decentralized digital currency supported by a large community of supporters
the differences between bitcoin cash and bitcoin are as follows:
BCC removes segwit, cancels the restriction of 1m block size, supports 8m block size at most, and adheres to the expansion route on the chain.

9. BCC inherits almost all of BTC's user base and has a wide range of exchanges and wallets. The large block owned by BCC can make the transaction faster and cheaper, which can truly realize the "point-to-point encrypted e-cash system" mentioned in the bitcoin white paper. This is unmatched by bitcoin in the short term,
BCC community is composed of supporters and developers of large blocks, and supporters of large blocks have shown great strength in the fight for capacity expansion. The developers of BCC are composed of a group of smart programmers. The development team includes bitcoin XT, bitcoin classic, bitcoin unlimited and bitcoin ABC, which basically covers all the large block development teams and has strong technology R & D capability. In the future, these technical teams plan to deploy such fashionable technologies as lightning network and smart contract on BCC.
