Bitcoin's computing power difficulty reduced
The following is the distribution chart of computing power:
the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing
however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p
-
it is estimated that 21 million pieces will be excavated in 2140
-
according to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow any more. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, the "proction time of each block is 10 minutes" used in the above calculation method is an ideal state, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error
the shortcomings of the above methods are that they can not accurately predict the change of bitcoin network computing power and the mining speed of bitcoin. The 11.3-day data used in the above calculation method is only the average value from May 2013 to April 5, 2014, and the representativeness is questionable. We can integrate the results of big data analysis and mining machine proction to establish a more accurate mathematical model
but bitcoin mining as an infrastructure, if bitcoin can continue to exist, although the income of mining is reced, for the security of the whole bitcoin network system, some big bitcoin companies may invest in mining to maintain the security of bitcoin network system. In addition, the future of bitcoin will become more clear and bright. Bitcoin's computing power will not decrease, but will increase.
At present, foreign bitcoin trading platforms show that the peak value of bitcoin trading price has exceeded the US $7400 mark, and it is also a wave to US $7500. At the same time, bitcoin cash (BCH) is also rising with the tide
it seems that the rise of bitcoin price drives the whole money market, so there is the rise of bitcoin cash; But is that really the case
in fact, bitcoin cash is different from bitcoin. The biggest difference is that the block capacity of the blockchain is 8m; Similarly, it does not recognize segwit, which is a new branch of bitcoin compared with the capacity of the original 1m bitcoin block
user needs also determine the price
whether it's real goods or the digital currency virtual goods we are talking about, it's just with user needs that they are created. Although the price of bitcoin cash (BCH) has been hovering around $300 before, from the current price of bitcoin, there is still a lot of room for the rise of bitcoin cash (BCH); Is the rise of bitcoin's cash price not in the form of user demand
BCH has great development prospects
BCH is the digital currency most in line with the original heart of bitcoin
the original intention of Nakamoto's design of bitcoin is to be a kind of currency widely used by human beings, a point-to-point currency which is different from the current legal currency system and cannot be eliminated by power. In order to achieve this goal, bitcoin network must keep the transaction fees at a very low level, so that all users feel indifferent; The second is to give users a stable confirmation expectation, that is, 10 minutes to confirm. But now bitcoin is off track. Bitcoin cash (BCH) is based on this point-to-point e-cash system to improve
increase in computing power
the rise in the price of bitcoin cash is also inseparable from the mining computing power of bitcoin cash. With the increase of the mining difficulty of bitcoin and the decrease of the mining difficulty of BCH, the miners think that it will be easier to dig BCH, and it is more profitable to dig bitcoin cash (BCH) than bitcoin, so the computing power will switch to BCH. With the rising price of BCH, digging BCH will become more profitable
bitcoin will be bifurcated again, which is good for BCH
bitcoin will be bifurcated again in November, which is good for bitcoin cash. Because the consensus of the bitcoin community is not consistent, bitcoin is likely to become two kinds of coins after the bifurcation in November. The newly generated bitcoin with the capacity expanded to 2M and the non expanded bitcoin will compete for the naming right of "bitcoin". The fight for naming right will bring great economic chaos and replay attack, which is a threat to users' assets. Some users will move to the bitcoin cash (BCH) camp in order to preserve their assets. If segwit2x hard fork fails in November, bitcoin cash (BCH) will be used as a solution for bitcoin expansion, and will gain more users' support e to its own advantages. Therefore, before the bifurcations of bitcoin come, some investors will invest in BCH to avoid risks, which will also cause a wave of rise
the continuous improvement of bitcoin cash (BCH)
there have been many supporters since BCH came into being. With the continuous development of BCH, many trading platforms, infrastructure, businesses have joined the BCH camp. Because BCH has the advantages of low transaction fees and reliable transaction confirmation that bitcoin does not have at present, it is inevitable for BCH to recover the territory lost by BTC e to transaction congestion and soaring costs in the future. At present, BCH community has been comparable with BTC community
BCH's surge is inevitable. Because the emergence of goods is to meet people's needs BCH, as a point-to-point e-cash system which is most in line with Nakamoto's idea, is very promising. With the development of time, it is possible for BCH to surpass BTC in price as well as in value
