Jingdong mining and selling knife group
mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
extended data:
shortcomings
first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

SFU GPA algorithm
math 3 credits a = 4
eng 3 credits C = 2
Chem 4 credits B = 3
GPA = (3 × 4+3 × 2+4 × 3) / (3 + 3 + 4) = 3.00
the algorithm of UBC is the same, but the algorithm of fail is different
after SFU and fail, retake and GPA calculate the second score
after UBC and fail, retake and GPA calculate both times, for example, Chem fails for the first time and C for the second time, then 8 credits and GPA, that is (4 + 3 + 4) × 0+4 × 2) / (4 + 4) = 1.00
I don't know how the domestic universities require the subjects they haven't passed
1. There are many majors that are easy to get employed. The key is how much space you want to develop in the future. Generally speaking, accounting is relatively easy to get employed, but now it's too much to learn, but it can be considered. There is also a new major, actuarial science. There are fewer students and it is easy to get employed. However, the requirements are very high, and only SFU has this major. It depends on your situation. Computer science is OK.
2. The requirement of business is relatively high. Recently, counsellor of UBC came to Langara. I read his form. This year's GPA of business class needs 3.50, which is still very high, because a - is 3.67, and you need to reach 3.50, which is very important, that is, volunteering. Some people's GPA is not so high, but they can transfer to UBC, But some people have enough marks, but they can't go. The main reason is your volunteering, which is very important (for business). You can't remember how many hours it takes. Moreover, volunteering should be comprehensive, not only in one place, but also with different volunteers
3, Congratulations, it's OK to go directly to university courses. In fact, to be honest, leap is not very useful.
4. LPI is a big problem. In the past, the policy was better, but now there are new requirements. If you transfer to UBC two years later, you have to finish two English courses, English 1127 and 1129, in the "first academic year". If you delay, for example, if you finish these two courses in the second academic year, you need to score 5 on the LPI. If you come to Langara, you can read 1127, then you don't need to take the exam.
5? Where to go? It's not clear whether it's Langara or UBC. If it's Langara, it doesn't matter if there is no college entrance examination score
6. What you need to provide is the results of seven examinations, which are the first and second semester of senior high school, the second semester of senior high school, the third semester of senior high school, and the results of the HKCEE. The requirement is not high, pass on the line, that is, they foreigners say C, of course, the higher the score, the better, to help the future course selection. The average score is about 80-90.
7. If you work hard, what can't you do? Have more confidence in yourself ~ ~
if you don't turn to UBC, we can turn to SFU. Ha ha, but if it's business, the requirements of SFU are the same as UBC, so work hard
it's not easy to do if you don't transfer, because Langara has two kinds of courses, one is career, which takes a college diploma, and the other is transfer. If you don't transfer half of your transfer course, you may not get that diploma
in this case,
the best way is to transfer to kwentlen (kuntland), which is very easy and requires less, and then you can get a diploma. Yes, it's University, because this school is also university now, so it's OK to look for a job, because it's the same university
it's almost so much~~~~~~
2. Environmental engineering cooperates with UNBC. Go to UNBC in the second year, come back in the third year, and go back in the fourth year.. It is said that UNBC was extremely cold that winter
3. Go to the Department of UBC applied science. You have to go to UBC and take some courses that Langara doesn't have, such as apsc150, before you can enter the second year's sub major system. Otherwise, it seems like it's enough. You can ask the engineering office, phone number 604-822-6556

As a result, they left a deep impression of bloodthirsty in human subconsciousness. Although the orcs have abandoned this tradition of banditry for a long time, when the orcs migrated to human society, human beings still formulated strict policies against them, resulting in the orcs' almost complete marginalization.
