Diggingtrojan digs digital currency
mining Trojan horse is now in the limelight, and its gold sucking power is catching up with blackmail virus. Recently, 360 security guard intercepted a Monroe coin mining Trojan horse spread by "eternal blue". Due to carrying heavy attack ammunition, the Trojan horse spread a large amount, reaching 100000 times a day at the peak, and 360 recently intercepted more than one million attacks
it is understood that this is a large-scale attack of mining Trojan horse carrying "eternal blue" against ordinary Internet users. In order to prevent computers from becoming the coolie of hackers mining, 360 reminds Internet users to ensure that they are well patched and immune to all kinds of attacks using "eternal blue", and at the same time, 360 security guard is opened to comprehensively defend against all kinds of mining Trojan horse

just like bitcoin ten years ago, you can mine with ordinary computer, which is awesome
the money you have g up can also be traded in the exchange or cashed out quickly, which is absolutely refreshing.
2. Digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

2. Customer service: certification business, enjoy one-to-one exclusive services, exclusive standards, join the certification business community, etc
3. Applicable rules: Certified merchants are required to abide by the rules more strictly than ordinary merchants, and super merchants are required to abide by the rules more strictly than certified merchants
4. Scope of application: global businesses support foreign currency transactions (US dollar, Singapore dollar, etc.).
Digital currency appears and has more and more influence, but it is impossible for digital currency to become a unified currency and replace paper currency unless governments unite, because it is a conflict between national interests{ RRRRR}
we assume that one day digital currency will be unified, and it can become a good medium for intermediate exchange, avoiding the risk of foreign exchange filtering. Of course, it stabilizes the international financial system and avoids the huge losses of buyers and sellers caused by foreign exchange fluctuations, which is of great benefit to the development of international trade, but the disadvantage is that, Whether this thing is reliable or not depends on time. not all countries recognize this thing. If people don't recognize this currency, they won't trade with you. This is also possible strong>
undergraate courses are divided into three categories: basic courses (Advanced Mathematics, physics, linear algebra, probability theory, mechanical drawing, etc.), professional basic courses (theoretical mechanics, rock mechanics, engineering mechanics, etc.) and professional courses (mining, ventilation, mining machinery, disaster prevention, etc.), In the first two years of undergraate ecation, only basic courses and professional basic courses are generally taught. High school courses are the basis of these courses, but they are only the basis. If you want to learn well, you still have to work hard<
I'll focus on professional courses for you.
1) physics, theoretical mechanics, rock mechanics and engineering mechanics
mechanics is a compulsory course for engineering students. Some schools also offer blasting mechanics, elastic mechanics, damage mechanics, etc. their learning methods are similar to those of high school physics, but they pay more attention to practice. Personally, I think it's still very difficult, Mechanics must be learned well< 2) mining, mine ventilation and safety
the professional courses of mining are relatively easy to learn< Electrical and electronic technology
Electrical and electronic technology should be included in the professional basic course. The electrical part of high school physics is the foundation, and there are many experiments in this subject, which have both principles and applications, so it is quite difficult! It is also difficult for a miner to learn a mine electrician
4) mining machinery
mainly learn the working principle of mining machinery, and only learn the principle. The updating speed of mining machinery is very fast, and many of the machinery in books are eliminated. This course is very simple
5) management and technical economics
engineering students all want to learn management, that is, some management methods and so on. It's not practical, but it's fun
technical economy is very important, but it is also simple. Some concepts, such as profit rate, profit and tax rate, payback period, etc.
just understand
all of the above are personal opinions. I hope they can help you. It's not a waste of me typing for half an hour!
