Chinese saying "we can see the rise and fall of history". If history knows the future, we can look at the development of the ETH and the ETC. The price of the former is $348.98, while the latter is at $16.36. It is clear that bitcoin and bitcoin cash are on a different path. Although many investors are surprised by the excellent performance of bitcoin after hard forks in August 1st, there is no answer to whether bitcoin will go the same way as Ethernet.
In 2014, the Bank of England had proposed that the future of encrypted currency was dead. In short, the miners have to compete in order to verify the transaction of the next block and obtain the transaction costs. As a result, their income depends on their ability to mining, or the "hash rate". The biggest problem, however, is that the difficulty of mathematical problems in the design increases with the increase in the amount of computing in the network. So, if other miners upgrade, miners will not be able to get more income from the mine. Marginal cost of investment will eventually be more than mining. Then, the miners will stop working and the bitcoin will fail. It is this mechanism that drives it from success to failure.
The bank's core argument is that the difficulty of growing faster than the progress of computing power brings the rate of cost saving to the market. In recent years, the growth of computing power is almost impossible to follow Moore's Law (the law is the law that predicts the exponential growth of the processor with time). It is difficult to refute the bank's view unless the currency's algorithm is modified to allow greater scalability.
If the point of view of the Bank of England was too pessimistic and far fetched, it would be important to stand today's point of view. Assuming the Bank of England's prediction marks the end of bitcoin, the problem is whether bitcoin and bitcoin will be different in valuation. Predominance still occupies a strong force in the encrypted currency. Bitcoin still occupies the largest market share, despite the emergence of the etheric and bitcoin cash on the market. The new money wants to beat the 7 - year - old currency is a feat.
On the other hand, bitcoin cash is more efficient than traditional bitcoin. Because compared with the original bitcoin, each block can carry out more transactions, all of which are because BCC has removed the isolation verification (SegWit), canceled the block size 1M limit, can support 8M block size, and adhere to the expansion line on the chain. Therefore, unlike the former challenger, the BCC is dominant in the process of competing with BTC. BCC has the same structure as BTC, which means that the old bitcoin community can be easily transferred to the new bitcoin environment. At present, once the price of BCC has recovered, the original miner may find it more profitable to dig BCC, thus switching the force to the cash of bitcoin. More importantly, according to the Bank of England, the lower transaction cost can be converted to a lower marginal cost, which will become an inflection point where the cost is equal to the cost. But this time may be later than the original bitcoin. As a result, bitcoin cash will live longer with lower transactions. After all, the block chain brings higher security, lower transaction costs, and more important efficiency.

conclusion：Bitcoin has jumped to $4200 from the initial 2700 dollars, but its support is still very few. The rest is bitcoin's network effect. Bitcoin cash is a big improvement compared with the original bitcoin. In this highly efficient market, getting more users is only a matter of time.
