Can bitcoin investment really make money

1. Credible. As long as he buys low and sells high, he will surely earn money. However, bitcoin is too risky. Consider his own capital and see if it's abundant. If it's just a little money, don't touch it. In particular, bitcoin futures, you may not have any money left in an instant, and you may even owe money if you have no time to close your position.

2. The price of bitcoin has gone up abruptly, and the old miners who left the mine have begun to return. Many new people have also poured into the mining instry. However, the price has gone up, and the difficulty of mining bitcoin is also rising. How can we make money from mining now
- - talking about the mining cost of bitcoin -
the first thing to consider is the cost if you want to make money. If the profit is greater than the cost, it is worth doing. We all know how much bitcoin costs, so let's calculate the cost
1. Mining machine cost: the "number" of bitcoin is a problem-solving process, which can't be calculated by human brain alone. Therefore, mining people need to buy mining machines and keep calculating. The more mining machines, the stronger the computing power
2. Electricity charges: mining machines are big consumers of high power. How much electricity does it consume? Let's put it this way. At present, the electricity consumption of bitcoin and Ethereum mining has surpassed Jordan, Iceland, Libya and other small countries, ranking 71st among all countries and regions in the world. You want to cry when electricity is expensive
3. The rent of the place where the mining machine is placed: because the mining machine consumes a lot of electricity, the power supply load of ordinary residential buildings can not be guaranteed at all, so the mining must rent a commercial site separately, and the rent is much more expensive than that of ordinary residential buildings
4. Operation cost: in order to ensure the computing power, the high-power mining machine needs to work 24 hours, which requires someone to maintain it at any time. When the mining machine is in trouble, the cost of hiring someone is required; At the same time, the mining machine is very delicate. If it is too hot or too cold, the vegetables will be stopped. Therefore, the measures of cold air and cold water insulation are needed to help the mining machine run. This is another expense
5. Mining machine update cost: because bitcoin is becoming more and more difficult to dig, the machine that was able to dig a month ago may not be able to dig anything today, and the market will also launch mining machines with greater computing power. The original mining machine is not worth money immediately. If you want to maintain computing power, you need to buy mining machines again
the above bitcoin mining costs all have a marginal effect, that is, the larger the volume is, the lower the corresponding cost will be. Therefore, some super large mines have been built
bitcoin g in the mine will enter the mine pool and be distributed by all participants. Large mines will be built in places where labor and electricity are cheap, such as Venezuela, the legendary miner's paradise, or Iceland, where the climate is favorable and electricity is cheap
as for the cost, everyone will be different. Let's take a look at an average: in 2017, according to the data of elite fixtures, a research institution, Venezuela is the cheapest of 115 mining countries, which is 513 US dollars, while South Korea is the most expensive, which is 26170 us dollars
China's mining cost is US $3172, which is relatively low among 115 countries. However, the cost is an average value. Large mines with low electricity prices must be much lower. If you are a lone ranger, the cost will rise sharply
in a word, if you really want to make money by mining, first of all, unless you are rich enough to build a mine with thousands of machines, you'd better join a mine to dig together. Although you have to share the money, it's still appropriate in the long run because it can greatly rece costs and improve computing power
secondly, whether you dig by yourself or join the mine, you must choose the place with low electricity cost, and the city with abundant hydropower resources is preferred, because hydropower is the cheapest source of power generation in China at present.

3. Very suitable for long-term investment
bitcoin has increased 100000 times in the previous decade, and it will become the future currency in the next decade.

4. If you describe it more clearly, I would like to answer this question
I have been working in a mine and trading coins for many years.

There are risks

on the one hand, the Internet real name system can become the "iron broom" to sweep away bad information, on the other hand, it will make all Internet platforms become "fat meat" in the eyes of hackers, increasing the risk of personal information leakage of Internet users

according to the analysis report on the situation of personal information leakage from websites in 2016 released by 360 patch day vulnerability platform in March 2017, 58.5% of the website vulnerabilities in 2016 will lead to the leakage of real name information, 62.4% of the website vulnerabilities will disclose behavior information, and the number of possible leaks can reach 4.23 billion and 4.01 billion

according to insiders, hackers often get users' registration information on Internet platforms and sell it to lawless elements by "scanning numbers and colliding libraries", but many platforms still lack effective defense measures against this "colliding library attack"

extended data:

holds up the "umbrella" of personal information for real name netizens

the major Internet platforms graally improve their own defense systems from both technical and regulatory aspects to prevent hacker attacks from leading to user information leakage. It is understood that a security team has been set up on an Internet shopping platform to discover high-level persistent threats on the internal network based on the security risk detection and identification of network security attacks, mine and detect phishing websites targeting buyers and businesses, and deal with them in a timely manner

the relevant departments of the state have successively issued various laws and regulations to ensure the information security of Internet users

"China's" decision on strengthening the protection of network information "," tort liability law "and its judicial interpretation and a series of legal provisions have repeatedly stressed the issue of personal information security. It can be seen that China's network information security and personal data security have been raised to the highest level of the country, and strict legal proceres and clear legal authorization are required for the use and collection of personal information. "

Zhu Wei, deputy director of the communication law research center of China University of political science and law, believes that under such a background, the comprehensive establishment of the real name system can actually strengthen the personal information security protection of users

6. It's just a kind of virtual currency. Making money only depends on luck. Maybe it will be worthless at any time.

7. Earn a fart, China has banned trading, you know what it means, is that you have a lot of money before Qing Dynasty, you can't use it now

8. This year, bitcoin will halve for the third time.

'I believe that the price of bitcoin will exceed $100000 in the next two years, and I stick to that prediction,' former bitcoin China CEO Bob Lee said in a recent interview. In the end, I believe the price will reach 1 million or more, which is the biggest investment opportunity in our life
however, the bitcoin market fluctuates strongly, and any investment will be accompanied by risks. It's better to test your risk tolerance before investment, because bitcoin investment depends not only on the market, but also on the attitude of investors, and resolutely refuses the gambler style. Finally, we wish all the people in the coin circle a big profit in 2020.

9. Bitcoin contract can make money, but it should be done in the right direction. Once it is wrong, it will be in debt very quickly. It is recommended to invest cautiously and wish you good luck. I'm really interested in contract trading. I suggest you go to okex exchange to learn and practice.
