Blockchain investment and financing risk
Although driven by the influx of capital and talents, the blockchain instry ushered in rapid development, but as an emerging instry, the frequent warning of its security vulnerabilities caused people to worry about the risk of blockchain
Yu Kequn, director of the national information technology security research center, pointed out that the emergence of blockchain has brought people a lot of expectations for privacy exposure, data leakage, information tampering, network fraud and other issues. However, there are still many challenges in the security of blockchain
Li Bin, assistant director of China Information Security Evaluation Center, analyzed that the current blockchain is divided into three types: public chain, private chain and alliance chain. No matter which type, it faces security challenges in algorithm, protocol, use, time limit and system. What is particularly critical is that the current blockchain is still facing 51% attack problem, that is, nodes can successfully tamper and forge blockchain data by mastering more than 51% of the network examples
it is worth noting that in addition to external malicious attack risk, blockchain also faces the threat of its endogenous risk. Yu Kequn reminded that how to build a complete security application system around the equipment, data, application, encryption, authentication and authority of the application system of the whole blockchain is an important problem that all parties must face
Wu Jia also analyzed that as an emerging instry, employees in the blockchain instry are lack of safety awareness, which leads to the low safety factor of the software and hardware related to the blockchain and a large number of security loopholes. In addition, there are many ecological links in the whole blockchain. In contrast, the strength of the relevant security employees is scattered and it is difficult to form a joint force to solve the problem. A systematic solution is needed to meet the above challenges

The risk of any investment is directly proportional to the return. The key is whether you dare to participate in it. Of course, there are too many uncertainties in the current blockchain instry, not because of the instability of technology, but more because some insatiable people are black hearted and hard to defend
in my opinion, bitcoin is the most popular blockchain derivative currency at present, and there is no one. Then there are many other counterfeit currencies. If you hold some bitcoin now, but you are short of bitcoin, it is equivalent to a risk. And you are facing this risk. In the normal way, you can hardly short bitcoin to make profits, unless you do some up and down options to hedge the risk. I have done some short-term options in extreme NEW Europe, Long term options are not recommended, and few platforms can. Bitcoin doesn't operate in the same way as foreign exchange, so it has profit opportunities. When you are bullish, you can buy or hold money. When you are bearish, you can throw money. When you hold money, you can only hedge it by buying options, so the risk is relatively high
according to the current bitcoin market, if this position is at the bottom again at most, it will hit the top edge of the box. In short, this range fluctuation will increase. If there is a wait-and-see, you can wait until you fall to the bottom of the box and try to buy it. You must set a stop loss, or you will be confused when you are buried. If you think bitcoin is too expensive, you'd better find some options to get addicted to it
facing the use of voltage generally 480 V, although one installation uses 4160 V, shielded cable end. Many textile mills and processing plants use 480 V distribution, with 2300 fifth very large delta often connected, so that plant action may continue, even if a stage becomes grounded, but these systems are equipped with ground display lights, and usually have special fault tracking equipment, so that the first stage to ground fault can be detected and isolated
other plants use a solidly grounded or resistor grounded circuit to trip with a selective earth fault. Heavy copper chains extend from the construction of steel frames, each motor providing grounding in most plants. In addition, the 480 V line is usually run on a metal conctor, which is often used as an additional ground conctor, which is ultimately bonded to the substation ground bed. Conctor ground command can be good for low resistance paths, if continuity is guaranteed in each union and flex coupling vibration, if not a problem. However, in some installations using shake head screen size separation, especially in sand and gravel or dredge plants, vibration may be so severe that the wire can literally be unshakable into pieces. In these cases, the conctor did not make enough frame grounding conctors
most surface mine visits also utilize resistance grounded system circuits to feed portable and mobile devices powered by trailing cables. However, at least one facility uses a floating delta secondary if there is no grounding conctor. Theoretically, the ground fault current cannot flow in a delta system, but in reality it does because of the stray capacitance circuit. In addition, if two nearby devices have progressively failed to frame at different stages, a person who involves both machines at the same time will be shocked with a full range of line to line voltages. Ungrounded systems pose a significant risk to personnel unless they are equipped with a very sensitive GFI type trip, which is not available except for 120 volt circuits. All rake access utilizes shielded trailing cables, and their power system is equipped with resistance
thirdly, there is a risk of overvaluation. At present, there is no detailed or convincing pricing mechanism. It is more likely that the project initiator will proce a pricing based on the needs of the project development or his own understanding, which may lead to the so-called stage high investment< Fourthly, investors are too optimistic. Investors may see more space for future ICO projects, but in fact, from a slightly long-term point of view, there can be no sustained huge profits
fifthly, it is difficult for investors to control the stock risk of the project. After the completion of the project, there is often a certain development cycle in the follow-up. How to develop the project and how to promote it. Few ICO projects have clear plans for future development. This means that investors can't control what they can do after they invest their money.
just like in troubled times, people who rise up may fall to the ground or become the next emperor. The question is, do you dare
