Bitcoin out

Recently, the award-winning sentiment of the winners of a company's annual meeting spread in the circle of wechat friends: "first of all, I sincerely thank the company for rewarding me with 10 bitcoins worth 630000 yuan, and I feel lucky that I can win the prize worth 590000 yuan. Next, I'm going to make a good plan on how to use the 570000 yuan, after all, 550000 yuan is not a small amount...". Although it's just a joke, the price of bitcoin has been falling as it said

some analysts also believe that the trading price of bitcoin once fell below US $6000 before the chairman of the Commodity Futures Commission (CFTC) and the securities and Futures Commission (SEC), the two major US regulators, testified in the Senate on February 6 because of concerns about the US government's strict supervision. According to the testimony of CFTC and SEC presidents, they believe that Congress should consider expanding the scope of supervision of cryptocurrencies such as bitcoin, because most of these assets are not subject to investor protection laws

It has been ten years since the birth of bitcoin, and the price of a single bitcoin has broken through the $40000 mark, which has attracted more and more people's attention. And the trend of bitcoin is more and more like a bubble. Strong>, however, in the short term, the bubble will not burst in the short term, and it will probably be cracked until the bitcoin is close to digging. Of course, the bubble will break up mainly depends on the capital of the speculation when what time to leave, if the capital does not leave the field, the bubble will continue to . p> According to the above two points, the rising price of bitcoin is more like the last craziness of bitcoin and the last means for capital to make money. Although it is not known how long this method will last, but because of the characteristics of bitcoin itself, it can not replace traditional currency as a means of daily life. , when people no longer recognize their value or do not need it, then the bubble of bitcoin will burst instantly. P>

generally, no one can accurately determine the time of bursting of bitcoin bubbles, because it is related to what time the bitcoin will be g and what time the capital will leave. p>

By midday, bitcoin had fallen to around $10700. Bitcoin's previous attempt to break through $12000 failed, and yesterday's downward trend continues to this day. As a result, the cryptocurrency market fell, with 90 of the top 100 currencies falling

in the past 24 hours, according to the okex platform, the net outflow amount of bitcoin reached 638 million yuan, and according to the currency security data, the net outflow amount of bitcoin reached 152 million yuan. Although the capital outflow in the past 24 hours is relatively large, it has decreased compared with yesterday's capital outflow, and bitcoin has hit the bottom of US $10600 for many times in the past 24 hours. However, in terms of trading volume, there is strong support in this position. After that, we still need to observe the withdrawal of funds, so as to confirm whether the market goes up or continues to fall below the down. In fact, the so-called "bear market" in the currency circle is more popular than the "three o'clock community" before. In my opinion, I basically dare to assert that there are makers in the currency circle who have successfully harvested a batch of "leeks" by using some financial means or big men. This view may sound like "conspiracy theory" to many people, But I have to admit that speculators are everywhere in the coin circle. Zhu Xiaohu's warning that "I hope you don't stay in history because you reap leeks to earn money with blood" also has a certain basis in my opinion

the craziest time was in December 2017, when bitcoin reached more than 100000 yuan. Before that, people who invested in bitcoin could make a fortune overnight. At the end of 2017, the price dropped to below 40000 yuan, and there was also a correction in 2018

there are two ways to invest in bitcoin

one is to buy bitcoin directly and wait for it to rise, that is, simply buy it low and sell it high. Judging from the historical data and the popularity of blockchain, there is still a lot of room for bitcoin to rise, but the cost of this investment method is relatively low, and the price of bitcoin fluctuates too much, so although the income of buying bitcoin directly is high, But the risk is also great

the other is to "dig" bitcoin with professional equipment. The total amount of bitcoin is 21 million. mining is the only way to get bitcoin, that is, through a professional computer, which is called mining machine in the instry, to get bitcoin through a lot of calculation, and then sell bitcoin to get income. At present, the price of a mining machine is about 10000, Another problem is the cost of electricity. This kind of equipment consumes a lot of power and needs 24-hour uninterrupted operation, so after a long time, the electricity cost is not a small cost

at present, there are many people engaged in mining, mostly in the form of mines, finding cheap electricity for centralized mining to rece costs

every day will generate income, the highest is more than 200. In addition, the fluctuation of the currency price has little impact on the mining, because the bitcoin can be sold at any price. Even if the price of the coin is low, it can be sold after the price rises. Therefore, the investment income is relatively stable, the risk is relatively low, and the current machine price is also low, There is no threshold for investment, so it is a good opportunity for investment

compared with self built mines, it has certain advantages to invest in mining machinery trusteeship business. Firstly, the time cost is saved to a certain extent, and the mining business can be started immediately. Secondly, unnecessary expenses, such as labor cost, are saved. Since the custody business concentrates the mining machines of multiple investors in one mine, the labor cost is shared by all investors. Finally, there are cheaper electricity prices. The ultimate goal of hosting enterprises to carry out mining machinery hosting business is to make profits. If they can not get lower than the normal electricity price on the market, it is difficult for hosting enterprises to make profits. Of course, the electricity price given to investors will also be lower than the normal electricity price on the market. Another important advantage is that some trusteeship enterprises are able to cash the virtual currency g up by investors' mining machines directly, which also relieves some investors from the worry that they can't cash the virtual currency

is mining profitable or not? There are several factors affecting the mining income: first, the currency price. The higher the currency price, the more profitable the mining. The second is the difficulty. The slower the difficulty rises, the more profitable the mining will be. The lower the cost, the more profitable the mining. Of course, the cost here refers to the purchasing cost and operating cost of computing power, including labor, network, construction, electricity and so on. The lower the cost, the better. Mining needs to deal with the risk of currency price plummeting, mining difficulty soaring, and mining costs rising. At present, the risk of mining currency speculation is much smaller

now the currency price continues to fall. Some people say that it's better to buy money directly than to buy a miner. In fact, it's not the case. Buying money must bear the risk of currency price falling, and the risk and income coexist, while buying a miner is to "protect the income from drought and flood" and keep the value of money rising; In the absence of rich market experience, the decision to buy money is only the choice of speculators

If you compare the decline of bitcoin with the rise of bitcoin at that time, you will find that such a decline will not have any impact on bitcoin. However, this time bitcoin's decline actually sounded a signal that bitcoin has indeed lost its original popularity. Now many people are keen to invest in bitcoin as an important investment channel. Because of his crazy rise, many people have opened bitcoin investment accounts. But here I still want to warn you that investment is risky, especially for virtual currencies such as bitcoin. So today we will discuss whether the popularity of bitcoin has dropped{ RRRRR}

Third, how to look at the current situation of bitcoin

among all the answers about bitcoin, I always insist on the idea that as an investment channel, bitcoin is really not worth your investment, because as a virtual company or it has no credit endorsement. So it could collapse at any time. The price of a bitcoin has exceeded 200000 yuan, which is unacceptable to ordinary people. So in daily life, if you are advised to invest in bitcoin, you must be careful and understand that any investment is risky

It can be seen from the figure:

1. From the distribution box to the lamp, there are three lnpe

2. An N-In line, when the switch appears, the number of poles will be increased. For example, when the lamp reaches the secondary switch, there are three lines between the lamp and the switch. That is, one incoming line, two outgoing lines, a total of three

4. Among the same group of lamps controlled by the same switch, there are three lnpe

5. Between different groups of lamps controlled by the same switch, l n plus the number of groups of lamps behind the line. If there are other switches connected below, add another L line that does not pass through the switch

extended data

the basic return route of common control lines is composed of the following parts

1. Power supply circuit: the power supply of power supply circuit includes AC380V and 220V

2. Protection circuit: the working power supply of protection (auxiliary) circuit includes single-phase 220, 36V or DC 220, 24V, etc., which can protect electrical equipment and lines from short circuit, overload and voltage loss, and is composed of fuse, thermal relay, voltage loss coil, rectifier component and voltage stabilizing component
