Friday is the last trading day of November, and this day is also November 30.

If we continue the previous state of mind, today when the stock index gapped, opened low and dived quickly in the afternoon, Lu Jin, Jinfugui Building, came to them, and sighed again.

It's just that the market is changing rapidly, and Lu Jinlai and they are also looking for a good solution, and they sold out the stock on Thursday.

When the market jumps down and falls fiercely, the bears can be happy.

"Let's see, as of November 30, only four equity fund products have achieved positive returns this year. CIFM Healthcare topped the list with a yield of 5.25%, followed by Sino Strategic Select with a yield of 3.61%. The other two positive return fund products are Golden Eagle Information Industry and Bank of Communications Pharmaceutical Innovation, with returns of 1.12% and 0.13% respectively since the beginning of this year. If we don't clear our positions, we will still be up and down in the sea of suffering?"

"Yes, I think Bitcoin is a genius idea, and I looked it up, and on November 1, 2008, a man who called himself Satoshi Nakamoto posted a discussion on a cryptography comment group about his new vision for electronic money — and Bitcoin was launched, and the first transaction of Bitcoin was completed. Bitcoin uses the disclosure of the distribution ledger to get rid of the constraints of third-party institutions, which Satoshi Nakamoto calls a regional chain. Users are willing to dedicate their CPU computing power to run a special software to be a miner, which will form a network to maintain the blockchain together. In the process, they also generate new currencies. Buying and selling also extends on this network, and the computer that runs this software solves the irreversible cipher puzzles, which contain several buying and selling data. The first "miner" to deal with the problem will be rewarded with 50 bitcoins, and the relevant buying and selling area will be added to the chain. As the number of "miners" increases, so does the difficulty of each puzzle, which keeps the productivity of bitcoins in each buying and selling area at about 10 minutes. In 2009, Satoshi Nakamoto devised a digital currency, namely Bitcoin, and the booming Bitcoin market rose and fell. When the news of Satoshi Nakamoto being found broke, it quickly became the most attractive news on the Internet. Contrary to speculation that it may be a fictitious name, Satoshi Nakamoto is a real name, a 64-year-old Japanese-American who likes to collect model trains, has worked for large corporations and the U.S. military, and has done classified work," Lu Jinlai said at length. Compared with fiat currencies, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes, anyone may participate in the creation of bitcoin, and can circulate all over the world, can be bought and sold on any computer connected to the Internet, no matter where they are, anyone can mine, buy, sell or receive bitcoin, and in the process of transaction outsiders can not identify the user's identity information. In 2009, Bitcoin was created, which is not controlled by central banks and any financial institutions. Bitcoin is an electronic currency consisting of a complex string of computer-generated code, new bitcoins are created through a preset program, and as the total amount of bitcoins increases, the rate of new coins is slowed down until the total amount of bitcoins reached the limit of 21 million in 2014, and the total number of bitcoins mined has exceeded 12 million. ”

"How did Bitcoin come to be developed, it sounds a bit like a genius idea, but how can this American, who is a descendant of the Japanese, really think about it?" asked a researcher.

"The Bitcoin network generates new bitcoins through mining. The so-called mining is essentially the use of computers to solve a complex mathematical problem to ensure the consistency of the distributed ledger system of the Bitcoin network. The Bitcoin network automatically adjusts the difficulty of the math problem so that the entire network gets a good answer about every 10 minutes. The Bitcoin network then generates a new amount of Bitcoin as a bounty to reward those who get the answer. When Bitcoin was created in 2009, each bounty was 50 Bitcoin. Ten minutes after its birth, the first batch of 50 bitcoins was generated, and the total amount of money at this time was 50. Since then, Bitcoin has grown at a rate of about 50 per 10 minutes. When the total reaches 10.5 million (50% of 21 million), the bounty is halved to 25. When the total reaches 15.75 million (5.25 million new outputs, or 50% of 1050), the bounty is halved to 12.5. First of all, according to its design principle, the total amount of bitcoin will continue to grow until the day when it reaches 21 million more than 100 years later. However, the growth rate of the total amount of bitcoin currency will be very slow in the later period. In fact, 87.5% of all bitcoins will be mined within the first 12 years. Therefore, from the point of view of the monetary aggregate, Bitcoin will not reach a fixed amount, and its monetary aggregate will actually continue to expand, albeit at a slower and slower rate. Bitcoin is a virtual currency on the web that is available in limited quantities, but it can be used for cash: it can be exchanged for the currencies of most countries. You can use bitcoins to buy virtual items, such as clothes, hats, equipment, etc., in online games, and you can also use bitcoins to buy real-life items as long as someone accepts them.

On September 9, 2014, eBay announced that its payment processing subsidiary, Braintree, would begin accepting Bitcoin payments. The company has partnered with Bitcoin trading platform Coinbase to start accepting this relatively new means of payment.

While the eBay marketplace and PayPal business do not yet accept Bitcoin payments, Braintree customers such as Airbnb, a travel home rental community, and Uber, a car rental service, will be able to start accepting the virtual currency. Braintree, which is primarily a payment processing software for businesses, was acquired by eBay last year for about $800 million. On the evening of January 22, 2017, Huobi, Bitcoin China and OKCoin announced on their official websites that in order to further curb speculation and prevent violent price fluctuations, each platform will start to charge transaction service fees from 12:00 noon on January 24, 2017, and the service fee will be charged at a fixed rate of 0.2% of the transaction amount, and the active transaction and passive transaction rates will be the same. Li Liangying said, although these are all from Baidu Encyclopedia, but those who have read Baidu Encyclopedia always know a little more than those who have not read it.

To be honest, the idea of Bitcoin really opened the minds of these financial students.

Or maybe you feel like your brain is blowing.

And they also want to know what is legal and what is not, so that they can deal with it in the future.

"The advantages of Bitcoin are obvious, it has five aspects (from Baidu Encyclopedia)1, it is completely centralized, there is no issuing agency, and it is impossible to manipulate the number of issuances. Its distribution and circulation are realized through the open-source P2P algorithm.

2. Anonymous, tax-exempt and supervise-free.

3. Robustness. Bitcoin is completely dependent on the P2P network and has no issuance center, so there is no way to shut it down externally. The price of Bitcoin may fluctuate, crash, and many governments may declare it illegal, but Bitcoin and Bitcoin's vast P2P network will not disappear.

4. No borders and cross-border. Cross-border remittances will go through layers of foreign exchange control agencies, and transaction records will be recorded by multiple parties. But if you trade with Bitcoin, you directly enter the numeric address, click the mouse, and wait for the P2P network to confirm the transaction, and a large amount of money will pass. It does not go through any regulatory authority, and there is no record of cross-border transactions.

5. It is difficult for copycats to survive. Since the Bitcoin algorithm is completely open-source, anyone can download the source code, modify some parameters, and recompile it to create a new P2P currency. But these copycat currencies are vulnerable and vulnerable to 51% attacks. Any individual or organization, as long as they control 51% of the computing power of a P2P currency network, can manipulate transactions and currency values at will, which will constitute a devastating blow to P2P currency. Many altcoins are dead in this link. The Bitcoin network is robust enough that the number of CPUs/GPUs required to control 51% of the computing power of the Bitcoin network will be astronomical. But he has a significant drawback, which is that the price is extremely volatile. Due to the intervention of a large number of speculators, the price of Bitcoin for cash has been on a rollercoaster ride. This makes Bitcoin more suitable for speculation rather than anonymous transactions. ”

"How is it speculative?" said most of the researchers, looking inquiring.

"Haha, let's discuss this next time, let's do the current work well. ”

The researchers were thoughtful, but soon devoted themselves to the group, doing the support and the opening of the account, and it felt like opening a new world.

And this weekend, they are also very passionate overtime, everyone is watching the number of accounts opened keep beating, and their hearts are also beating.

It was an extraordinary weekend.
