Is fire coin the largest virtual currency trading platform in Ch

2. In China, there is no formal virtual currency trading platform. So don't think about it, wash and sleep.

3. Don't be fooled. China does not recognize the legitimacy of any virtual currency.

4. It's unreliable. Virtual currency has no real value. It's not a real currency, and there is no credit endorsement for it. It's not like that RMB and US dollar all have credit endorsement from big country government. This kind of virtual currency is greatly affected by human manipulation, policy risks, and the government does not allow transactions

5. There is no formality.
bitcoin is the most famous virtual currency. First of all, it has been seven years and eight months since its birth in 2009. From being worthless at first, it rose to 8000 yuan / piece in 2013, and even attracted Chinese aunts to join. With the regulatory policy crackdown in 2014, bitcoin once fell to about 1000 yuan, and then entered the bear market channel. It was not until the beginning of this year that a new round of bitcoin market broke out, hovering at a high of 4300 yuan / piece< However, the attitude of the regulators is clear. Whether it is genuine bitcoin, or a variety of derivative Shanzhai coins, there is no way to obtain legal living space at present. This is something we need to be clear about. If the platform goes out of business or the staff runs away, it is very likely that they will lose all their money and the losses they have suffered will not be protected by law
the promises they give you often make the participants pay money quickly. Behind them is the Ponzi scheme of "robbing the east to pay the west" + "cheating the white wolf with empty hands". They use the money of new investors to pay interest and short-term return to old investors, so as to create the illusion of making money and cheat more investment. When no new investors enter, the return of old investors collapses one after another, and it is often difficult to withdraw cash, or the website cannot be opened
in short, although the external form of virtual currency is ever-changing, it is not divorced from its essence of pyramid selling. The more investors put in, the greater the final loss, and the more serious the loss may be.

7. Click NNTool in the command bar and follow the prompt to submit the sample
another simple way is to use the generalized RBF network, which can be realized directly with GRNN function. The basic form is y = GRNN (P, t, spread). You can use help GRNN to see the specific usage. The prediction accuracy of GRNN is good

generalized RBF network: from the input layer to the hidden layer is equivalent to mapping the data in the low dimensional space to the high dimensional space, and the number of cells in the input layer is the dimension of the sample, so the number of cells in the hidden layer must be more than that in the input layer. From the hidden layer to the output layer is the process of linear classification of data in high-dimensional space. The learning rules commonly used in single-layer perceptron can be used. See neural network foundation and perceptron
note that the number of neurons in the hidden layer is greater than that in the input layer, and it is not equal to the number of input samples. In fact, it is much less than the number of samples. Because in the standard RBF network, when the number of samples is large, many basis functions are needed, the weight matrix will be large, the calculation is complex and prone to ill conditioned problems. In addition, compared with the traditional RBF network, the wide RBF network has the following differences:
1. The center of the radial basis function is no longer limited to the input data points, but determined by the training algorithm
2. The expansion constant of each radial basis function is no longer unified, but determined by the training algorithm
3. The linear transformation of the output function contains threshold parameter, which is used to compensate the difference between the average value of the basis function on the sample set and the target value
therefore, the design of generalized RBF network includes:
1. Structure design -- the hidden layer contains several nodes, which is suitable
2. Parameter design -- the data center and expansion constant of each basis function, and the weight of output nodes.

8. Hello, most of these platforms are not compliance channels, or even illegal,
but there is no problem, so it can not be determined
few investors and poor liquidity; Lack of supervision and serious manipulation.

9.

Without the so-called formal platform, virtual currency has not been legally recognized in China. There are only relatively large platforms, such as: among the top ten digital currency trading platforms that users are familiar with,

three digital currency trading platforms with an average daily trading volume of more than 10 billion are okex, fire coin pro and coin an

there are many digital currency trading platforms, more than 100 of which are still increasing. So many digital currency trading platforms make users dazzled when they choose

but in fact, although there are many digital currency trading platforms, there are few formal currency trading platforms that have done well in all aspects. The usage habits of every user who invests in digital currency procts will also affect their evaluation of the selected digital currency trading platform

extended information

in order to protect the interests of investors, the regulatory authorities have long announced the prohibition of this transaction in China - and the regulatory authorities' determination to crack down on virtual currency transactions has not changed

you know, as early as September 2017, the central bank and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, calling for the suspension of direct transactions of virtual currency. In January 2018, the leading group for the special rectification of Internet financial risks, the China Internet Finance Association, the business management department of the central bank and other departments successively issued three articles to strengthen the supervision of virtual currency again
