2. The pain point of asset securitization business is that the authenticity of underlying assets cannot be guaranteed; There are many participants, many operation links and low transparency of transactions, resulting in information asymmetry and other problems, which makes it difficult to control the risks. The data pain points lie in the low efficiency of the flow among the participants, the large amount of manpower and material resources needed for the fund clearing and reconciliation between the transaction systems of all parties, the online and offline multiple channels of asset collection, and the inability to monitor the real situation of the assets. There are also problems of trust in the authenticity and accuracy of the underlying asset data of all parties in the transaction chain after the formation of the asset package

Change: the characteristics of blockchain disintermediation, consensus mechanism and non tampering can increase the efficiency of data flow, rece costs, monitor the real situation of assets in real time, and ensure the trust of all parties in the transaction chain on the underlying assets.

3. Blockchain is an emerging instry, which has been highly valued by all countries. It is called the fourth instrial revolution and will have an immeasurable impact on society. Blockchain is the literal translation of block and chain. Each block stores the transaction data within a specified time, and forms a non tamperable, all staff shared distributed ledger through cryptography
digital currency and virtual currency are actually different names. They are tokens issued based on blockchain technology. Behind them are a series of computer-generated complex codes. At present, there are thousands of digital currencies in the market. The safest and most powerful digital currency is bitcoin
digital currency is also a high-risk and high return investment proct, through appropriate investment strategies, you can get rich returns. If you have spare money, you might as well put some of it into the digital currency. There will be unexpected surprises.

4. 1. Bitcoin
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.

Drawing method:
connect two or more relative low points into a straight line to get support line
connect two or more relative high points into a straight line to get pressure line
usage:
1. The function of support line and pressure line
support line is also called resistance line. When the stock price falls near a certain price, the stock price will stop falling and may even rise. The price that prevents the stock price from continuing to fall or temporarily prevents the stock price from continuing to fall is the position of the support line
pressure line is also called resistance line. When the stock price rises to a certain price, the stock price will stop rising, or even fall back. The price that prevents or temporarily prevents the stock price from rising is where the pressure line is

The function of support line and pressure line is to prevent or temporarily prevent the stock price from moving in one direction. At the same time, the support line and pressure line have the possibility of completely preventing the stock price from changing in the original direction
2. Support line and pressure line transform each other
If a support line is broken, it will become a pressure line; Similarly, if a pressure line is broken, it will become a support line. This shows that the position of support line and pressure line is not unchangeable, but can be changed, provided that it is broken through by effective and strong enough stock price changes< Generally speaking, the importance of a support line or pressure line to the current impact has three aspects: one is the length of time the stock price stays in this area; the other is the length of time the stock price stays in this area; Second, the trading volume of stock price in this area; The third is the distance between the occurrence time of this support area or pressure area and the current period

In addition, there is another kind of asset with the characteristics of anonymity. Its main functions include protecting the privacy of both sides of payment while realizing payment.
