Is it bitcoin that skylex returns

1. 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.

2. Don't be extravagant. I suggest you go online and have a good look at the instructions of bitcoin
to sum up, there are two simple points: first, the golden age of bitcoin mining has already passed, especially for indivials who are absent from work. It's hard to make up for the electricity charges of those who only have losses but no profits. Unless you have a unit dedicated computer for you to use, 24-hour power on non-stop digging. But this is still a loss, just unit for you to pay the cost, you take advantage of the unit
the second is configuration. Your configuration is too poor. Now mining is basically done with high-end a cards. It's necessary to connect several top graphics cards in parallel, such as 7970. You don't know how many generations behind. People don't necessarily earn money by digging with top-level cards, not to mention your one.

4. Bitcoin mining, mainly through the algorithm to obtain bitcoin, and in the bitcoin system, basically every 10 minutes, there will be a node mining success, and once someone mining success, bitcoin system will reward a certain number of bitcoin, and this number is controlled by the algorithm

and the principle of bitcoin mining is POW algorithm, which is workload proof algorithm. In short, it's a proof that you've done a certain amount of work

5. How can dpos balance the advantages of centralization and decentralization
share authorization certification mechanism, dpos for short, is similar to the voting of the board of directors. The coin holders cast a certain number of nodes to verify and account on their behalf. In order to encourage more people to participate in the election, the system will generate a small amount of tokens as a reward. Bitstocks, diandianbi and other digital assets use this method
dpos is a bit like the parliamentary system or the people's Congress system. If representatives can't perform their ties, for example, when it's their turn to keep accounts, they will be removed and the network will select new nodes to replace them
each client of dpos has the ability to decide which nodes can be trusted. Compared with pow (workload proof mechanism), dpos greatly improves the ability of blockchain to process data, and can even achieve second arrival. At the same time, it also greatly reces the cost of maintaining blockchain network security, so that the transaction speed of digital assets is close to that of centralized settlement systems such as visa.

6. Great wisdom is a real-time market display and trading system software
there are many functions, not only transaction information, but also other policies and company information that can be linked
you will know when you use it.
some shortcut keys are also very useful, such as those defined in the K-line state:
F1 is the transaction record of each order in time-sharing; F3 Shanghai index time-sharing chart, F4 Shenzhen index time-sharing chart
F6 select the sector of the stock pool; F7 current affairs information; F8 various K-line change display
f9f12 is transaction entrustment; If you are new to the stock market, it is recommended that you invest a small amount of money first,
wait until you have accumulated experience to a certain extent, and then do it.
I hope you can make small gains and big gains...

7. The revenue of bitcoin is based on bitcoin every day. The rise and fall are calculated. If it's long, it's positive. If it's down, it's not. Haha, I suggest that my friends try not to play for him, because the price of bitcoin is very high now. If you buy it now, it's the order taker. It's going to hold you tight. And you'll lose a lot of money. So stay away from bitcoin. hey

8. Yes, the income is high. The recent rise is very good~

9. False, you can simply calculate by yourself. If you invest $500 according to 5% of the daily income, you will get $27.1 billion in return one year later, and you will be able to reach the top of the rich list immediately. But the cost of all this is only $500 and one year. Do you think this kind of good thing can happen? What's more, it's only $500. If you invest $5000, $50000 or more, you will have the global wealth in your hands one year later. Such a good thing will only happen in your dreams

10. You have too many questions to answer here

the handling charge is a discount, not a refund. I have the impression that the contract is up to ten times

you can buy stable bitcoin, usdt usdk and then bitcoin

blockchain is a distributed decentralized account book

for example, the current bank data is managed by itself, and programmers can tamper with it

if blockchain technology is used, data can be saved by many computers and recorded separately. It can't be tampered with.
