Bitcoin finance channel

1. Fire chain finance is the wind vane of bitcoin news instry

2. As a bitcoin player, after watching this issue of Caijing Lang Yan, I feel that it is necessary to correct Professor Lang's unprofessional knowledge of bitcoin:
1. Bitcoin allocation mechanism:
the mining allocation mechanism of bitcoin is not that 50 out of 10000 people (that is, miners) are divided into 50 bitcoins, but that only one out of 10000 people can get 50 bitcoins
it sounds unfair, but the existence of a mine pool is equivalent to a group of miners digging for bitcoin. If 10000 people form a team, any one of these 10000 people gets 50 bitcoins. According to the team agreement, everyone shares equally according to their contributions. More work pays more, less work pays less. The income from more contribution is more than 0.005, and the income from less contribution is less than 0.005, And as long as there is contribution, no matter how bad the computer is, it will have income (just can't make ends meet), forming a relatively fair distribution mechanism
2. Is bitcoin a currency?
bitcoin, as its English name is bitcoin, has never claimed to be a currency, but a payment system or accounting unit similar to a coin. Now it is meaningless to discuss whether bitcoin is a currency. Currency is a commodity separated from commodities and used as a general equivalent
the development of bitcoin is still in the process of practice, and it is far from being separated from commodities and becomes a fixed general equivalent. If it fails in the fixed experiment, bitcoin is not a currency; If it succeeds, bitcoin will be the historical alternative to legal currency. The good news is that the experiment has a trend of success so far
3. The intrinsic value of bitcoin
in the program, the CEO of bitcoin China couldn't answer the intrinsic value of bitcoin, but used an ambiguous price to refute, even angrily asked if you want 100 bitcoins, and was defeated by Professor Ying. I admire Professor Lang's wisdom, but I also regret that Professor Ying has no relevant computer knowledge and does not understand the intrinsic value of bitcoin
back to the point, what is the intrinsic value of bitcoin
bitcoin itself is worthless. It's just a string of codes, a number for bookkeeping. It's worthless, but the price is outrageous
what is really valuable is the bitcoin protocol! But this agreement is open all over the Internet
for example, there is a price for domain names on the Internet. A good domain name is still very expensive, but the domain name is just a string of characters and has no value. The whole Internet is used arbitrarily. The Internet all over the world uses exactly the same internet protocol. Only on top of the protocol can there be a large number of domain names. However, the internet protocol has become the cornerstone of human information society, on which many high price services are derived
it's amazing that those with value have no price, while those with super high price have no value
to explain the value of bitcoin protocol in one sentence: the honesty of payment between people is entrusted to mathematics and supervised by the whole network
you may not believe the person you trade with, he may cheat you, but you can believe that 1 + 1 is always equal to 2
bitcoin is characterized by decentralization, constant total amount, impossibility of counterfeiting and simplified proceres
4. Bitcoin connection problem
the program repeatedly talked about who is more stupid than bitcoin and who will play the last connection game
when bitcoin was first invented, I don't know if it was for your wealth, but with the development of bitcoin today, people who exchange legal money for bitcoin are really trying to win more wealth. Those who own bitcoin in the early stage earn those who enter the market in the later stage. The people who enter the market now also want to earn money from those who enter the market in the future. Let's imagine that the last one who comes into the game can't make any money if he has bitcoin and has no family. Moreover, the development of bitcoin has been as I said before. We all know the characteristics of bitcoin, but what choices do bitcoin owners have at this time
A. keep holding against inflation - the price of bitcoin is stable at a high level (because no one takes over)
B. throw bitcoin around - the price of bitcoin drops
C. exchange commodities with the merchants who accept bitcoin - the currency of bitcoin
in view of these three situations, let's think again
a. the price is stable at a high level, indicating that there is no large-scale selling, the price of bitcoin is stable, there is no inflation, and wealth is not plundered implicitly, which makes it a general equivalent suitable for money. Because the legal currency will be graally abandoned in devaluation, bitcoin will win completely
B. the price of bitcoin drops sharply. During the slump, there will be countless people waiting for the bottom, because we all know that the agreement of bitcoin is anti inflation, and it is worth preserving compared with legal currency. Therefore, people who didn't have time to buy coins at a low price in the early stage will continue to buy bitcoin until bitcoin drops to the bottom, and the bottom hunters will rush on, eventually making bitcoin a higher price commodity, Become the last runner of the new bitcoin. And this answer is also contrary to the assumption of the last one who came into play before us
C. bitcoin, as a supplement to legal currency, acts as a general equivalent
to sum up, if bitcoin is likely to develop normally, it will go through the process of becoming a supplement to legal currency, and then replace legal currency to become a currency. Of course, this is an extremely long and difficult process, and it may also fail
5. The concept of Chinese aunts in bitcoin
specifically refers to a group of Chinese retail investors who rush to buy gold ring the gold price crash in 2013, because in China, the main consumer group of gold is aunts, who have the capital strength, no relevant knowledge and experience, and the courage to make crazy investment
ring the period of the sharp rise and fall of bitcoin, the concept of Chinese aunt speculation on bitcoin also spread
according to a large number of statistics, 93.6% of bitcoin players are male, and they are 20-40 years old, and most of them have bachelor's degree or above. Of course, quite a few of them have financial strength, no bitcoin related knowledge and experience, and have the courage to make crazy investment. If people with these characteristics are called Chinese aunts, they are indeed a cold joke
according to this concept, the CEO of bitcoin China who argued with Professor Lang in the program also belongs to the group of Chinese aunts.

4. Iexotc is OK, mainstream virtual currency can be seen, IEX currency is OK.

5. It will be very difficult, 0.0

6. The address will be checked, so the wrong address cannot be sent. Sending to the address where the private key is lost can be successful. That's just another form of bitcoin suicide!

7. The voice of justice, now wechat has a stock exchange group called Wenyuan finance and economics lecture hall, set up an organization called JingWuMen, now Wenyuan lecture hall is pushing bitcoin to investors, investors must not speculate, this is a fraud. This teacher named Wen Yuan is Han Ze, who used to be in the lecture hall of dragon crossing the river and crouching tiger, hidden dragon. The original organization was Ze Ying Hui. At that time, he pushed us to sell Hong Kong myth coins. After buying the coins, the whole cheater organization lost contact. At this time, he found that only one or two of your group were real people, and the rest were Tuo. This mythical coin incident made us lose money. Some people borrowed money from their families behind their backs. Some retired aunts took out all the money for their old age. As a result, their wives got sick and had no money to see a doctor. Some people are now separated from their children, and some have the idea of suicide. The ultimate goal is to sell their various digital currencies, futures, CSI 300, Hong Kong stocks, open the so-called banker's capital channel, Dow index, stock index and so on, and defraud your blood and sweat line. Wake up, there's no free lunch. What has happened, call the police immediately and trust the strength of the people's police.

8. The mainstream doesn't recognize it

9. blockchain
the underlying development can't be realized with Java
the upper development only needs to dock according to the given open source interface, and then develop what you need with the language you are good at
now there are many blockchain system templates, you can go to see which development cases are there
