1. Rx470 and rx570 are the most cost-effective ones (before 1500), and their mining performance is no worse than 480 and 580, but they are much cheaper. We can also consider the lower 460 and 560, and other models are not worth considering.
2. Firstly, the cost of bitcoin mining can be divided into three parts:
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.

Eth is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0", and uses the blockchain technology "Ethereum" which is different from bitcoin
it is an open-source public blockchain platform with smart contract achievements and a resonance network composed of thousands of computers around the world. Developers need to pay eth to support the application. Like other digital currencies, ether currency can be bought and sold on the trading platform
Technical Architecture:
the smart contract endows the account book with programmable characteristics. Blockchain 2.0 realizes the function of smart contract by running code in the way of virtual machine, such as Ethereum virtual machine (EVM) of Ethereum. At the same time, this layer forms a decentralized application (DAPP) by adding a foreground interface that can interact with users on the smart contract
of course, in some technical documents, it is reasonable to think that DAPP should be a separate application layer above the smart contract layer, as long as it does not affect the understanding

6. Stock index is a positive proportional function of the market value of index portfolio, and its rise and fall range is the yield of the portfolio. But in the calculation of the stock index, the transaction cost of the stock is not dected, so the real income of the investors will be less than the rise and fall of the stock index, which is the maximum return on investment of the index portfolio
there is a common saying in the stock market, which is called "bull gains bear losses". That is to say, in a bull market, the investors make profits and lose money in a bear market. But if we analyze the investors as a whole, the investors may not be able to make profits in a bull market
1. If a bull market is reversible, investors will only lose but not make money. The middle point of Shanghai stock index is about 600 points. In the bull market in early 1993, Shanghai stock market broke through 1500 points, and then fell back to more than 300 points in July 1994; In September 1994, the Shanghai stock market hit 1000 points again, but soon fell below 600 points. Judging from the operation of the index in recent years, the Shanghai stock index always starts from below 600 points, forms a bull market and then returns to 600 points. It can be said that all bull markets in Shanghai stock market are reversible
when the Shanghai stock index rose from 600 points to 1000 points and returned to its original position, indivial shareholders may earn and lose money, thus transferring their wealth. But for this group of shareholders, they not only have no gains, but also have losses
first, no matter which point the transaction is at, the shareholders need to pay transaction tax and handling charges. The stock index rose from 600 points to 600 points again. For the investors as a whole, there is no return on investment except transaction costs. The trading volume of Shanghai stock market above this point should at least account for more than half of the total trading volume. For the investors, it is futile to spend less than half of the transaction fees and taxes, because the purpose of investing in stocks is to gain profits from the rise of stocks
secondly, shareholders pay an extra price for the rights issue and the issuance of new shares. When the index returns to below 600, it is equivalent to holding up for the investors who allot shares or buy new shares above this point. This holding up is different from holding up in the secondary market, because holding up in the secondary market is only a change of hands among shareholders, There was no loss of funds. However, after the high price allotment or purchase of new shares, the funds flow to the listed companies. This kind of hold up in the primary market is a huge loss to the shareholders as a whole. For example, the cost of issuing Tsingtao beer is about 12.8 yuan per share, but its net assets are only 2 yuan per share. That is to say, the shareholders spent 12.8 yuan to buy only 2 yuan of net assets. No matter what the opening price of the stock is later, the shareholders as a whole paid 12.8 yuan for each Tsingtao Beer stock. If the investors invest a share of Tsingtao beer in treasury bonds or deposit in the bank, they can get at least 1.3 yuan a year. No matter how promising Tsingtao beer is, its annual average income is difficult to reach such a high level. Therefore, in a reversible bull market, if we take the investors as an investment as a whole, the investors will only lose but not make money
2. Even in a bull market, shareholders may not be able to make profits. The rise and fall of the stock index is the return on investment of shareholders, but this return on investment is nominal and does not dect transaction costs. For some of the more mature western stock markets, because the annual turnover rate is only about 30%, the transaction cost is generally negligible. In China's stock market, e to the frequent turnover of shareholders, the turnover rate in recent two years is generally around 700. If the transaction cost is included, the income of shareholders in China is actually a negative number
in 1994, the tradable shares of Shanghai and Shenzhen stock markets proced nearly 5 billion yuan of after tax profits for the investors, but the total turnover of the two stock markets in this year was as high as 820 billion yuan. According to the unit turnover, the buyer and the Seller each need to pay 3I transaction tax and nearly 4.5i handling fee, the investors will spend 12 billion yuan of transaction cost, and the investors will also pay 7 billion yuan of transaction cost
although the composite index of Shanghai and Shenzhen stock markets is much higher than the base of 100 points at the beginning of counting points, according to preliminary estimation, by 1995, the listed companies in Shanghai and Shenzhen stock markets had only proced 10 billion yuan of after tax profits for the shareholders in the secondary market in five years, while the transaction fees and taxes paid by the shareholders in this stage were as high as 20 billion yuan
compared with 1990, although the Shanghai and Shenzhen stock markets are still bull markets, the shareholders as a whole are losing money, because the returns given by listed companies to shareholders can hardly offset the expenses of stock trading
3. If a bull market makes the stock price deviate from its investment value, the profit of shareholders is fictitious, and the profit of some shareholders is based on the loss of others. In the short-term bull market, the stock market may create an illusion that all shareholders are profit makers. In fact, this kind of profit is virtual, because the overall value of the stock is calculated by the transaction price of some stocks. When a stock is traded at a higher price, the market value of some non traded stocks will be calculated according to the transaction price. As a result, the book value of the shareholders who hold the stock increases. For example, more than 70% of the state-owned shares or corporate shares of Listed Companies in China are not listed in circulation, but some people often calculate the value of state-owned assets based on the market price of the shares. After the stock price rises, they think that the value of state-owned assets has increased. However, if all the stocks of listed companies enter into circulation, it will be difficult for the stock price to reach the current stock market level e to the sharp increase of stock supply. Therefore, the profit in the stock market can not be calculated by the transaction price of others, but can only be calculated by the transaction price realized when selling. In addition, when the stock price deviates from its investment value, the profit of some shareholders is based on the loss of others. If the annual after tax profit of a stock is 0.1 yuan, the current one-year savings rate is 10%, so the theoretical price of the stock should be 1 yuan. When some investors wildly speculate their prices to deviate from their investment value, for example, when they speculate their prices from 1 yuan to 5 yuan, the investors who buy 1 yuan and sell 5 yuan make a profit of 4 yuan, but the investors who buy 5 yuan lose 4 yuan, because the actual income of the stock is only equivalent to 1 yuan of savings. Therefore, in the stock speculation, it is generally the latter to buy in return, the first to buy, and the new investors return the old investors.
there is a common saying in the stock market, which is called "bull gains bear losses". That is to say, in a bull market, the investors make profits and lose money in a bear market. But if we analyze the investors as a whole, the investors may not be able to make profits in a bull market

Therefore, in the stock speculation, it is generally the latter to buy in return, the first to buy, and the new investors return the old investors.
7. Net profit / cost * 100% is the rate of return, which is different from annualized rate of return. Annualized rate of return is to consider the time factor, which is your level of return in this year. Those advertisements on the Internet do not include the time factor, so they don't tell you which period of time you get these high returns, which is not of reference value, especially the high returns in a short period of time
