More than half of bitcoin's computing power
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
Bitcoin bulls often mention that the scarcity value of this cryptocurrency is the main reason for its continued rise. Bitcoin is similar to gold to some extent. The growth of its supply is extremely slow, and it is still slowing down. Its total supply will only reach 21 million
with the increasing interest of institutional investors and retail investors in bitcoin, global exchanges such as the Chicago Board of options (CBOE) have launched bitcoin futures contracts. This is likely to encourage more institutional investors to invest in bitcoin, while at the same time further curbing the price volatility of bitcoin
this much anticipated bitcoin futures trading has been launched on the Chicago Board of options exchange, which represents a significant step in the legalization of cryptocurrency. Futures is a derivative / financial instrument, which can force dealers to buy and sell an asset at a specific time and price

unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk
warm tips: the above information is for reference only. Before investing, it is recommended that you first understand the risks existing in the project, and understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

Bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

for ordinary investors, the most important thing is the price of bitcoin. Does the rection of bitcoin proction next year mean that the price of bitcoin will rise significantly? In fact, from the trend of bitcoin after the first two proction cuts, we find that bitcoin will usher in a super market soon after each half cut. Proction rection can indeed stimulate the price of bitcoin to rise substantially. It is no exaggeration to say that bitcoin halving is an important catalyst to push bitcoin into a super bull market
in addition to ordinary investors, there is a group of people who are quietly paying attention to the price of bitcoin, that is miners! Nowadays, mining costs are rising, coupled with the competition for computing power, currency price fluctuations and other reasons, resulting in the extremely unstable income of miners. In addition, it should be noted that in 2020, with the rection of bitcoin proction and the new upgrading of mining machinery, the cost of mining will be even higher. If the price of bitcoin falls below the cost of mining, the high cost will make the miners have to shut down, resulting in the loss of investment in mining machinery, and finally lead to mine disaster
How do put options hedge the risk of bitcoin falling
recently, bitoffer is the world's first BTC option, which has no margin, no handling charge and no exercise, so it is the most suitable tool for hedging bitcoin spot risk
for example, the current price of bitcoin is $7000. If it goes up to $8000, you can make a profit of $1000 from the spot
What if it falls to $6000? You did not do any hedging, spot direct loss of $1000
if you hedge accordingly and open a put option in bitoffer, the cost will be about US $20-50. If bitcoin falls from US $7000 to US $6000, the put option will earn US $1000. In this way, the US $1000 of spot loss will be offset, and there will be no loss in the account. This is the charm of hedging.
The first half: on November 28, 2012, the 210000 block was excavated, and the block reward was halved for the first time, and the block reward was 25btc
the second half: on July 10, 2016, starting from the 420.000 block, the bitcoin reward of each block was halved to 12.5btc
the third half: on May 12, 2020, bitcoin reward will be halved to 6.25btc
the next half: on May 9, 2024, bitcoin reward will be halved to 3.125btc

in the very early days, when the computing power of bitcoin was very low, the computer could also carry out a lot of calculations according to the algorithm to "mine" bitcoin
when users "mine" bitcoin, they need to search for 64 bit numbers by computer, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a group of numbers, they will get the bitcoin awarded by the block. However, e to the rising value of bitcoin, the number of users of bitcoin mining is very large. There are millions of professional mining machines mining at the same time, and the output of bitcoin is very limited every 10 minutes. As a result, tens of millions of people scramble for a block. Therefore, if you use personal computers to mine alone, you may not be able to grab a block in a whole year, People came up with a method of group mining, so the mining pool was born. There are a lot of users who play after mining
I hope you will adopt it.
