"Gold and silver are not money naturally, but money is gold and silver naturally." this is a sentence Marx said about money
How to understand? In fact, it is very simple that money is the inevitable proct of the development of human life. In the earliest stage, gold and silver were only used as a kind of metal or a kind of ordinary commodity to exchange things. However, with the development of society, people find that gold and silver are easy to separate, easy to preserve, easy to carry and other advantages, so the suitability of gold and silver as currency is reflected, and naturally evolved into currencyWhat about bitcoin
1. Machine cost: the cost of purchasing mining machine
2. Power cost: the power cost consumed by machine mining
3. Auxiliary costs: personnel maintenance, network, cable consumables, heat dissipation, etc.
for a simple example, take the mining machine of ant S9, which consumes less power on the market, for example, the calculation power is 13.5T, and the power consumption is 1400W
when the mining machine runs for 24 hours: 1.4kw * 24 = 33.6 degrees
Shenma m3, which consumes more power on the market, has a calculation power of 11.5t, The power consumption is 2150w
under 24-hour operation, the power consumption of a single machine is 2.15kw * 24 = 51.6oc
which is roughly equivalent to the power consumption of energy-saving air conditioning, but the bitcoin miner needs 24-hour uninterrupted operation, the power consumption of a single machine is very large after a year's calculation, and the step price cost of household electricity is too high, When the market is not good, the income may not be enough for the electricity expenditure, so at present, mining will choose to be hosted in the mine, which can get cheap electricity and rece the cost price of mining. The price below 30% is the ideal price, which can keep the price of bitcoin falling to a low level, and there is still some income< According to the current mining difficulty of bitcoin:
BTC revenue per ton: 1th / s * 24h = 0.00007087btc
calculated by the comprehensive 12t machine computing power, the daily output is:
0.00007087t * 12t = 0.00085044btc
then the time required for a single machine to dig a BTC:
1 / 0.00085044 = 1175 days
the time required for ten mining machines to dig a BTC:
1 / 0.0085044 = 117 days
100 days In other words, according to the current difficulty, it takes about three years for a single miner to proce a bitcoin, 3.9 months for ten miners to dig a bitcoin, and 11.7 days for a hundred miners to dig a bitcoin. The cost of a single miner is about 8500, Ten are around 85000, one hundred is 850000, less than one million, and one month's income is more than two bitcoins. According to the current price of bitcoin, the price is about 120000. So, although the income of bitcoin mining is not as good as before, it is still considerable compared with other investment projects
however, these benefits do not include decting the cost of electricity charges and later maintenance of machines, so the premise of mining is to find a mine with low electricity charges. If the quantity is large, we need to find a safe, reliable and stable mine. What's more, we need cheap electricity to lower the cost price.
On January 3, 2009, the first batch of 50 bitcoins were g up on a small server in Finland. On May 21, 2010, the first bitcoin transaction: programmer Laszlo hanyecz bought a $25 pizza coupon with 10000 BTC. This transaction gave birth to the first fair exchange rate of bitcoin.

Satoshi Nakamoto, a self styled Japanese American, is often translated by Japanese media as the founder of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system. In 2010, he graally faded out and handed over the project to other members of the bitcoin community. Nakamoto is believed to hold about one million bitcoins. These bitcoins were worth more than $1 billion at the end of 2013since the publication of the paper, the real identity of Nakamoto has long been unknown to the outside world. Julian Assange, founder of WikiLeaks, claims that Nakamoto is a cypherpunk. In addition, some people said that "Nakamoto is an anarchist. His original intention is not to control digital cryptocurrency by a certain government or central bank, but to become a global free flowing currency that is not regulated and controlled by the government."
main entry: bitcoin history
on November 1, 2008, Nakamoto published a paper entitled "bitcoin: a point-to-point e-cash system" in the cryptography mailing list of "metzdowd. Com". This paper describes in detail how to create a decentralized electronic trading system, and this system does not need to be built on the basis of mutual trust between the two parties. Soon, on January 3, 2009, he developed the first client program to implement the bitcoin algorithm, concted the first "mining" and obtained the first batch of 50 bitcoins. This also marks the formal birth of bitcoin financial system
on December 5, 2010, ring the WikiLeaks leak of US diplomatic cables, the bitcoin community appealed to WikiLeaks to accept bitcoin donations to break the financial blockade. Nakamoto expressed his firm opposition, saying that bitcoin is still in its infancy and cannot afford conflicts and disputes. Seven days later, on December 12, he published his last article in the bitcoin forum, mentioning some minor problems in the latest version of the software. Then he did not show up and e-mail communication was graally terminated
Bitcoin is a kind of encrypted digital asset protected by cryptography, without the participation of centralized institutions. It has been running steadily since 2009 and has become one of the important investment targets of global investors. Many investors are very interested in bitcoin investment. The entry process of bitcoin and some investment procts is slightly different. The address of bitcoin blockchain is decentralized, so there is no account opening step. However, purchasing Mai bitcoin with bitcoin requires the assistance of some third-party platforms
at present, there are relatively large platforms in China, such as okex, fire coin and coin security. I have been in and out of money for many times in these platforms. Let's introce my experience of buying Mai bitcoin in these exchanges.
before the introction, I need to explain one premise: the security of Mai bitcoin is divided into two aspects: one is asset security, which basically won't cause any problems when I choose the three major domestic exchanges; the other is capital security, in other words, Is to rece as much as possible with the flow of black money bank card transactions. Because it's easy to freeze their bank cards, each exchange has a different strategy
1、OKEx: https://www.okex.me/buy-crypto/cny
okex is the exchange that I use the most Mai currency. I have been in okexmai currency since 18 years. Most of the time, I have had a good experience of Mai currency. I only encountered the problem of freezing okex account (not bank card freezing) once in my impression. However, OK customer service also helped me understand the freezing process very quickly. This is my first contact with OK customer service, Good attitude and high efficiency< it can be seen from the side that okex has done a lot of work in the prevention and control of black money. Moreover, in recent years, there are few card freezing incidents in okex. Today, the black money in the exchange is increasingly rampant, okex has done quite well
in terms of user experience, the function of one click Mai is more suitable for Xiao. When using this function, you don't need to select the businesses that meet the standard in the list of businesses. It's more convenient. At present, when you do activities, you will get a 20 yuan reward when you buy Mai for the first time
in addition, okex is a first-line exchange with a large user base. Mai currency supports wechat, and ZFB buys Mai with zero handling charge. If you've just come into contact with bitcoin, it's a quick and safe choice in okexmai
However, the weakness is that okex has little support for foreign currencies. Except for RMB, only the Vietnamese Dong and Indian Rupee have depth. The Mai currency entrance of other countries' currencies is only the interface of other cooperation platforms2 https://www.huobi.com/zh-cn/
the exchange's legal currency trading plate is deep enough, and there are many powerful businesses with good experience. Support the purchase of Mai bitcoin with multi currency. In addition, the process of making Mai coins is relatively smooth and can be completed in a few minutes
however, e to the good user experience of fire coin, black and gray procts will also choose fire coin as a channel for money laundering. fire coin has been updating its risk control strategy to intercept black money accounts. However, at present, it seems that the effect may not be so good, and the freezing card incident continues. Friends who pay close attention to the digital money market may understand that a large-scale freeze occurred in early June, and many users' bank cards were frozen. Therefore, we should be a little more cautious when using Mai coins on this platform, try to choose the ranked merchants, and rece the probability of being frozen.

the trading plate of currency security legal currency started late, and the accumulation was not enough. Frankly speaking, the depth and experience of legal currency trading is quite different from that of okex and fire currency< Strong>, especially the t+1 strategy of currency, which is Mai currency, will make complaints about money in a day. This system has been thrown into the trap by too many people, because this is obviously a "one size fits all" strategy with insufficient technical capability.
however, even if there are many slots, coin an is slightly better than the second and third tier exchanges in terms of asset security. Users who trade in coin an can also try to buy Mai bitcoin in coin an
finally, based on the above factors, it is suggested that okex is the first choice for Mai bitcoin, fire coin is the second choice, and coin security is not recommended strong>
high efficiency
blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
