1. If there is a problem with the source of bitcoin, it may not be limited to money laundering. Doesn't he own Alipay? Why don't you use your own? It doesn't do you any good.
2. There is no clear legal definition. Bitcoin is still a private proct. Bitcoin itself is not a formal currency, and there is the concept of no national boundaries in bitcoin, so many countries do not recognize it. Including China. Therefore, in the process of the transaction or the subsequent risks are only borne by the participants themselves. If bitcoin collapses one day, no country will rescue it.
3. There are two main ways to trade bitcoin in China:
one is to trade bitcoin on the trading platform. You need to register an account on the trading platform, complete real name authentication, and bind a bank card to trade bitcoin. The well-known bitcoin trading platforms in China are okcoin, bitcoin China, and huocoin.com
the other is over-the-counter transaction, which also becomes a third-party guarantee transaction. Generally, it is a large amount transaction. Zhao Dong in the circle has been doing relevant business
of course, another way is to use bitcoin to buy goods or services. There are many businesses around the world that accept bitcoin payment, such as Dell and Microsoft. Bitcoin house has more reports about companies and businesses that accept bitcoin payments.

4. The platform is suspected of illegal operation or the rules made by the platform itself are unreasonable
the trading of virtual currency is generally free, and no one can interfere. However, in order to rece the risk, some platforms will set a price limit, but they will not be frozen because the seller's price is too high. At most, they can't sell it. Prices can be freely quoted
none of the mainstream platforms such as bitcoin China, Xigu digital asset trading platform and jucoin will be frozen because of the high price.

5. A lot of calculation is to detect the operation speed of a mine pool. The higher the computing speed is, the more likely it is to win the bookkeeping right, that is, the packing of transaction flow. Why fight for bookkeeping rights? Because at the same time of bookkeeping, we can get the new currency. The higher the computing speed, the higher the input cost of the mine, or the more miners the mine contains. Just like the election of president, the one who spends the most money or has the most supporters should be the president. When you become president, you should also be honest. If you are not honest, the people can also abolish the president
the deeper meaning is: the higher the computing speed of an honest mine, the higher the computing speed of the mine that forges bitcoin. If he has invested his money in mining, but is making counterfeit money, if everyone doesn't admit it (we will certainly refuse the counterfeit money), isn't he going to lose all his money? It's better to dig the real money honestly. It's also cost effective.

6. 1，4 matlab是有帮助文档的，我没有明白你所指的去中心化处理是什么，PCA的结果在数组自己的维度
以下是帮助文档，请仔细阅读
coeff = pca(X) returns the principal component coefficients, also known as loadings, for the n-by-p data matrix X. Rows of X correspond to observations and columns correspond to variables. The coefficient matrix is p-by-p. Each column of coeffcontains coefficients for one principal component, and the columns are in descending order of component variance. By default, pca centers the data and uses the singular value decomposition (SVD) algorithm.
example
coeff = pca(X,Name,Value) returns any of the output arguments in the previous syntaxes using additional options for computation and handling of special data types, specified by one or more Name,Value pair arguments.
For example, you can specify the number of principal components pca returns or an algorithm other than SVD to use.
example
[coeff,score,latent] = pca(___) also returns the principal component scores in score and the principal component variances in latent. You can use any of the input arguments in the previous syntaxes.
Principal component scores are the representations of X in the principal component space. Rows of score correspond to observations, and columns correspond to components.
The principal component variances are the eigenvalues of the covariance matrix of X.
example
[coeff,score,latent,tsquared] = pca(___) also returns the Hotelling's T-squared statistic for each observation in X.
example
[coeff,score,latent,tsquared,explained,mu] = pca(___) also returns explained, the percentage of the total variance explained by each principal component and mu, the estimated mean of each variable in X.
2. PCA 和SVD的不同是，他们分解矩阵的方式是不同的我建议你翻看wikipedia里面SVD和PCA的说明，里面公式很清晰了

7. If you withdraw cash on weekends, you may have to wait until weekdays to get to the account. If you withdraw cash on weekdays, you can get to the account soon. If you don't get to the account, you are advised to consult bitcoin China customer service staff, who will give you solutions. Of course, you can also leave messages on its official WeChat official account or official website micro-blog.
8. It is suggested that you do not give the bank card handled with your ID card to others. If the other party does something illegal with this bank card, it is likely to involve you. ID card and bank card are important documents with personal information. It's better not to lend them to others.
9. Guangzhou Daily (Reporter Lin Xiaoli) recently, an investment model called "financial mutual aid community" has spread widely. It claims that the monthly income is 30%, and the annual income is 23 times, that is, 10000 yuan will become 230000 yuan in one year. Is this a pie or a trap
recently, the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce issued an early warning on this mode of mutual financial investment, reminding investors to pay attention to the behavior of promising high returns and luring investment in the name of "mutual financial assistance"
Miss Huang, who lives in Haizhu District, told reporters that she was recently drawn into a wechat group, an investment and mutual aid group, with a high interest rate of 30% per month“ Now that the stock market has adjusted and banks have cut interest rates, it's not easy to find such a high-yield project. My friend recommended this investment group. It's really tempting, but I dare not invest too much. I only invested more than 10000 yuan. " According to the 30% monthly interest rate, 10000 yuan will become 13000 yuan a month later; If it continues rolling for one year, the income can reach 230000, equivalent to 23 times of the principal< According to Miss Huang's guidance, the reporter logged into a platform called "MMM financial mutual aid community", and saw the most prominent slogan of "earning 30% a month", as well as various members' personal experiences
in this financial mutual aid community, the amount of investment is between 60 yuan and 60000 yuan, the fixed income is 30% interest per month, and the principal + interest can be launched as soon as 15 days. The platform says that when someone needs financial help, you will directly call the other party with your money; When you need funds, you can apply on the platform and wait for others to call you. In this way, you can make money by constantly offering and receiving help
MMM mutual aid community platform also set up "Management Award" to encourage members to develop new people. The "tutor" guides the new people to make money, and the tutor can get rewards
according to the publicity of the platform, the platform was founded in 2011 by Sergei mavroji, a Russian, and has 138 million members in 107 countries. Since coming to China in mid April, the number of members of MMM financial mutual aid community has exceeded millions
a person in the banking instry told the reporter that the rate of return on capital investment is not high when entering the channel of interest rate rection. The average annual rate of return on bank financial procts or P2P financial procts has dropped to about 10%, but the ultra-high interest rate of 30% per month is difficult to achieve“ Like this pyramid way, he can guarantee the recovery in the early stage. After a long time, an important foundation for this kind of scam to continue is that there will be continuous follow-up, and then the investors behind will suffer heavy losses. " According to the person
warning:
the fund operation is difficult to maintain for a long time
this mode has also attracted the attention of relevant departments. The CBRC and other departments recently issued the "early warning tips on the risk of obtaining high returns from investment in the name of" mutual financial assistance ", many of the features mentioned are very consistent with the" MMM mutual financial community ". According to the CBRC, the mode promises high returns and lures investment, often in the name of "mutual financial assistance"
participants can also get extra income such as recommendation Award (10% of offline investment amount) and Management Award (the corresponding proportion is determined according to the membership level), and there is no upper limit for development personnel and rebate. In terms of concealment, this type of website is controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank account or through the third-party payment platform
according to the CBRC, this kind of operation mode violates the law of value, and once the capital chain breaks, investors will face serious losses
