1.
mining chip has gone from CPU mining to GPU mining to FPGA mining, and now it has entered the era of ASIC mining. However, the way of mining has also experienced from one or two mining machines to small mining machine workshops, and now it has entered the era of large-scale mining
(1) mining mode: from one miner to large-scale mine
if you start to try mining, you need to prepare a miner, a computer with internet connection, an AUC, a raspberry pie, power supply and various connecting cables. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply
2. It's not worth it
bitcoin is no longer easy to dig, and it is much cheaper than before
maybe you can only dig for a few hours a day and lose money
even if you mine with a high configuration computer in your own home, it is estimated that you will consume a little more electricity, not counting the aging depreciation of the computer.

3. It may be this problem, or it may be the setting of the miner. You can ask the next pool operators or mining machine vendors. But you can't get much bitcoin with USB. If it's OK to experience mining, it's basically difficult to get profits from it.
4. According to the results of bitcoin mining income calculator on bitfan website:
income: 0.0009 BTC RMB & # 165; 3.09 US $0.50 (at present, the price of bitcoin is about 3600 US dollars, about 580 US dollars, and the mining difficulty is 18736441558)
the mining speed changes at any time according to the mining difficulty
this kind of Power Miner is only for those miners who want to experience mining. In addition to electricity and other costs, there is basically no profit. If you want to get more profit from mining, you have to buy more power miner
for example, the mainstream miner Avalon 290g single-mode miner in the market, you can choose to buy the T-class package.
income: 0.0009 BTC RMB & # 165; 3.09 US $0.50 (at present, the price of bitcoin is about 3600 US dollars, about 580 US dollars, and the mining difficulty is 18736441558)

6. Unreliable, easy to have problems
7. A 24-year-old female patient with recurrent sequelae of gas poisoning was treated with hyperbaric oxygen. In April 1993, the coal stove was moved to the room, and the patient felt uncomfortable in the precordial area. Then he fainted, vomited, and had no incontinence of urination and urination.
he was sent to the local hospital for treatment, and woke up the second day after oxygen inhalation under normal pressure combined with traditional Chinese medicine. In the past 4 years, the patient often had
convulsions (1 time per month on average), had premonition before the attack, had unconsciousness ring the attack, had limbs
moon curve, left neck turning, foaming at the mouth, and occasionally had fecal and urinary incontinence. Walking unsteadily, daily
drop cross 8 ^ - 8 times. He came to our department in November 1997 and denied any other medical history. When

normal. C D showed: no obvious abnormal diagnosis: acute carbon monoxide (CO)
sequelae of poisoning, epilepsy carbuncle, hyperbaric oxygen (iibo) treatment was started the next day, the pressure was increased by 15
min, the pressure was 0.a4 MP; Oxygen was inhaled for 20 minutes for 4 times, and oxygen was inhaled twice
compressed air in interphase breathing chamber.. 1， 30 mi, once per mouthful. At the same time,
zibamodipine 40 mg, coenzyme Q capsule 2 (1 mg, vedantamine 50 mg,
vitamin B, 20 mg and danacon 40 mg were given orally for 3 times,
after 12 times of HBO treatment, the patient walked more steadily than before, fell about 3 times a day, nystagmus
amplitude decreased compared with before, and stood unsteadily with eyes closed. H) to control bamboo; L 4 times later. The nystagmus of right visual SL
decreased significantly, and the vertical nystagmus disappeared. In the Spring Festival of 1998, he suffered from "La carbuncle" attack e to fatigue. When the attack occurred, his eyes were turned over. He closed his eyes tightly without warning. His upper limbs were bent and clenched. He had urinary incontinence. He was awake after 02-3nnu and had no memory of the attack. Electroencephalogram after seizure:
basically normal. In order to prevent epileptic attack, when HBO was given 3 times a day with 0-4 g sodium valproate tablets for 18 times, the nystagmus was significantly reced and the eyes were closed; Y
stable, no further drop in the situation_ EEG: EEG of normal alts. HBO
after 84 times of treatment, occasionally dizziness, nystagmus has been significantly reced, the frequency slowed down, the amplitude
reced, the "day inch" shortened. After 96 times of HBO treatment, nystagmus basically disappeared in left vision, and nystagmus still existed in right vision. Dizziness and nystagmus disappeared in 108 times of hilt treatment. The above drugs were continued after stopping IL HBO treatment. In May, 199, the drug was adjusted to sodium valproate 0.2 g, compound vitamin B: tablets, Yiganling 77
mg and gantaile 100 mg, three times per mouthful. At the end of antiepileptic therapy in March 3000, no abnormality was found in symptoms and signs of EEG after one-year follow-up
it is generally believed that CO and bo-1-6 enter the sequelae stage, and the patient's disease has been stable in Sui Dynasty, the value of treatment is very small, and the curative effect is poor, so it is generally not allowed to continue treatment. Although some people have tried to use amphetamine to treat some patients with sequelae of CO
poisoning and achieved certain curative effect, generally speaking, there is no effective treatment for this disease. Although the disease course of oral patients has been more than 4 years, they are completely cured after HBO comprehensive treatment, which is rarely reported, Recently, it was thought that the dead brain cells could not regenerate; In addition, some of them died at cell level, but had no function. There are three possible prognoses for this kind of cells: death, recovery of function and the status quo of
maintenance. If the treatment is appropriate, the metabolism of this part of cells can be improved, the number of dead cells can be reced, and the function of these cells can be restored, It may be related to the fact that there are still a considerable number of these cells in the brain. The use of Hb and its divination drugs can correct hypoxia, restore metabolism and functional reconstruction. Satisfactory results have been achieved. The recovery of the patient may be
accidental, but it can prompt the patients with sequelae of C () poisoning if there is one We should give up the chance of further treatment easily. The clinical effect of HBO and its drugs on the sequelae of poisoning needs further observation

8. Well, gas poisoning is also a headache for doctors. Its resial effect is very annoying and can be repeated. At that time, the treatment was almost complete, but it will be repeated and even aggravated after a period of time. Because CO poisoning can cause delayed encephalopathy and nerve apoptosis

9. Because the graphics card is not for mining, so the speed is slow. Mining machine can only mine, is optimized ASIC, so the speed is very fast. The average roast cat USB is about 300 + mhash / s, twice that of 5770. The average miner can be 5g-66ghash / s, faster than USB
10. Is the electricity bill enough.
