Abel's free digital currency

1. The methods to obtain digital currency for free are as follows:

1. Participate in the promotion of a certain currency
2. Gifts from friends or tasks
3
4
bitcoin, Ruitai coin and dogcoin have all carried out these activities.

2. The price of newly issued digital currency is generally very low, a few cents or even a few percent. It's easy for you to buy it directly when you dig. And now bitcoin can dig because its encryption algorithm is public. You can't dig all kinds of digital currency without public algorithm.

3. Exchange: bit-z
trading mining online time: June 2018
Project Introction: bit-z, founded in Hong Kong in 2016, provides digital asset trading and OTC (over-the-counter trading) services
dividend method: "transaction mining". Users who participate in the transaction can get a refund of service charge (in the form of equivalent BZ, and need to complete three-level certification); Each phase of 10 million BZ will be released step by step, and each phase of 10 million BZ will automatically enter the next phase. The return ratio of each period will decrease by 3%
total number of tokens issued: 1.2 billion BZ.

4. First of all, I would like to explain my point of view. I think there is no need to prepare for university courses. There is enough time for self-study in the University. Unless you want to get the highest scholarship and are really idle, you can take a look at advanced mathematics and physics, or download some books on coal mine geology from the Internet. Vacation is just for fun. Don't worry about things after school. Enjoy your holiday< However, since you have asked, let me talk about the curriculum of mining major:

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!

5. Proficiency is a must, so hurry to dig level 5 mines. In this way, it will be a little longer. Don't waste energy in digging low-level mines. If you have a full level of proficiency, you can upgrade it. If you upgrade, you can go to the gang to use tribute and gold.

6. Many Alipay users, landing accounts often appear this problem, Alipay synchronization is very accurate. The problem usually arises because every Taobao user has two accounts (a Alipay, a Taobao). If you look closely at the landing interface, you will find that a Alipay user has landed and a Taobao user has landed.

7. Now a lot of digital currency are illegal, playing digital currency risk is very big, do not recommend you play

8. I've been mining eco and RCO with my broken computer at home. The money I found can be quickly realized and made money when it comes to the coin easy platform!

"Abel" has four meanings

Nils Henrich Abel, a Norwegian mathematician in the 19th century

Niels Henrik Abel (August 5, 1802 April 6, 1829) is the greatest mathematician in Norway in the 19th century. One of his most famous results is the first complete proof that there is no general algebraic solution for a general algebraic equation higher than quartic. He is also a pioneer in the field of elliptic function and the discoverer of Abelian function

2, plastic materials

uses: electrical components, appliances. In the instrial field, it is used as switch, connector and parts under the hood of automobile

Advanced Boolean equation language, one of the three commonly used hardware description languages (Abel, VHDL, Verilog), is used to describe logic functions, which is convenient for designers to use PLD to realize function functions

4, Abel (biblical character)

Abel (biblical character), Cain, the father of the wicked, is his brother. Cain killed his brother because he hated him. Cain and Abel represent the two kinds of people in the world. Cain represents the people who commit crimes and think they are just. Abel represents the people who have sincere faith and fear God

extended data:

human civilization started from farming. With the increase of population and surplus labor force, the living resources near "Eden" are insufficient. So some people went to the sea to nomadize. They were Abel and Seth

in the Old Testament, "God" prefers the fur animals offered by Abel, a nomad, to the crops offered by Cain, a farmer. Abel was exterminated by Cain because he was nomadic in the farmland. "God" gave Adam Seth to replace Abel“ "God" demanded that the descendants of Seth should open up their territory and seek a place for milk and honey, instead of seeking revenge against Cain, the farmer, so as not to be avenged seven times

Farming in ancient times was a symbol of technology and diligence. In the understanding of Judaism and Christianity, Cain, by virtue of wisdom, diligence and strength, the Freemasons, who influenced the world's politicians in modern times, claimed that they were Cain's descendants in his propaganda

After Adam's crime, the crime not only entered the indivial's heart, but also continued to expand into the family and society. At first, people's crime is e to external temptation, and then, people's crime is malignant from the heart. It can be seen that after Adam's crime, man has a life of crime. Crime is not only e to the bad environment, but also out of the guilt of life
