1. They are:
bitcoin
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software was designed and released, and the P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
bitcoin cash
bitcoin cash is a new version of bitcoin with different configurations launched by a small number of bitcoin developers
extended data:
virtual currency refers to non real currency. Well known virtual currency, such as network company's network currency, Tencent company's Q currency, Q point, Shanda company's voucher, Sina's Micro currency (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver pattern (used for bixue Qingtian game)
the popular digital currencies in 2013 are bitcoin, Leyte coin, infinite coin, quark coin, zeta coin, BBQ coin, pennies (Internet), invisible gold bar, red coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"
2. BTC is bitcoin
LTC is lightcoin
eth is Ethereum
etc is Ethereum classic
3. The rapid rise of bitcoin's price comes from the fact that its use value is graally recognized by popular business services such as green ecology. For example, Jack Dorsey, the founder of Twitter and square, made a high-profile promotion and planning of BTC in Silicon Valley in the United States, which is also called the original ecological currency of the next generation Internet technology, and announced the purchase of $50 million BTC< naturally, apart from the Internet technology circle, it is also like the BTC Private Fund released by grayscale, a financial enterprise, which helps traditional financial enterprises get BTC financial planning
at present, the total position cost of BTC commodity futures is about 6.3 billion, which has increased 133% since the beginning of this year and constantly updated new historical records. Unlike the spot trading market, the increase of non compulsory position closing trading position of derivative procts in zero sum game indicates the contradiction level between buyers and sellers on spot trading base price
4. Not cost-effective. The total number of bitcoins is 21 million, and the
mining speed is halved every four years to be completed in 2140. Now the income from mining is very low, and the electricity charge is not high. So if you want to invest, you'd better buy bitcoin or other digital currencies directly. Suggest to go to a big trading platform, they will take the initiative to eliminate bad money into the market in order to maintain the reputation. For example, such as fire coin pro, which only has 100 digital currencies online, although some potential God coins may be eliminated, but generally speaking, they still have some bottom in mind.
5. Since the advent of the ball mill, the problem of the proportion of the ball mill is a problem that often puzzles people. Whether its preparation is reasonable directly affects the proction efficiency of the ball mill, and also affects the proction quality of the ball mill to a certain extent. So how to deal with the problem of the proportion of the ball mill and the steel ball? How to add steel balls to the ball mill according to the size ratio of steel balls? First of all, the steel ball ratio of ball mill in cement plant, mine site selection, thermal power plant and chemical plant should be determined according to the diameter of ball mill surface, ore hardness, ore particle size of ball mill, steel ball hardness (mass), ball mill speed and other factors. When the model of the ball mill is determined, the rotation speed of the ball mill is also determined, and the hardness of the ore can be determined. The particle size of the ball mill is determined by the size of the screen. Generally, the newly installed ball mill has a running in process. During the running in process, the amount of steel balls is added for the first time, accounting for 80% of the maximum ball loading of the ball mill. The proportion of steel balls can be adjusted according to the size of steel balls ф 120mm、 ф 100mm、 ф 80mm、 ф 60mm、 ф 40 mm). The amount of steel ball: different ball mill models have different total amount of ball. For example, mqg1500 × 3000 ball mill (processing capacity 100-150 tons) maximum ball loading capacity 9.5-10 tons. Adding steel ball for the first time ф 120mm— ф 100 mm), middle ball 80 mm, small ball 80 mm ф 60 and ф When the ball mill is installed, the big and small teeth of the ball mill need to be meshed, and the processing capacity (ore volume) also needs to be graally increased. After two or three days of normal continuous operation of the ball mill, stop the ball mill to check the meshing of the big and small gears, and wait until everything is normal, Open the ball mill inlet cover and add the remaining 20% steel balls for the second time. After the ball mill starts up and runs normally, the steel ball of each shift is added according to 3:4:3 ф 120mm is 3 ф 4 ф 80 mm is 3). Note: the addition of small steel balls is only the first time. Because the reasonable friction between steel ball and steel ball, steel ball and ore, steel ball and lining plate of ball mill ring normal operation of ball mill will increase the wear, and make large ball mill small (grinding to medium ball) and medium ball mill small ball. So usually under normal circumstances, there is no need to add a small ball. In the case of adding small balls, there is no monomer dissociation in the particle size of useful minerals. When the fineness of grinding machine can not meet the flotation requirements, appropriate amount of small balls can be added. The steel ball in the ball mill is constantly worn in the process of operation. In order to maintain the ball load filling rate and the reasonable ratio of balls, and maintain the stable operation of the ball mill, it is necessary to make reasonable ball replenishment and low compensation wear. The added weight of steel ball is based on the quality of steel ball, which determines the added amount of ore per ton. It is better to use a new type of wear-resistant steel ball. The best (good quality) steel ball addition is calculated according to the amount of ore per ton (i.e. 0.8kg per ton of ore added). Generally, it takes 1kg-1.2kg to treat one ton of ore with steel ball. The proportion of steel balls is different with different ball mill models. The diameter of the ball mill is less than 2500mm, and the size of the added steel ball is ф 100mm、 ф 80mm、 ф 60mm When the diameter of the ball mill is more than 2500, the size of the added steel ball is ф 120mm、 ф 100mm、 ф 80mm If you want to know more about the ratio of steel ball and ball mill body, please contact us Huamin steel ball.

6. The main cross-border e-commerce platforms at home and abroad are as follows:
1. International B2C cross-border e-commerce platforms: sumitong, Amazon, eBay, wish, Lanting Jishi, Dunhuang
2. Import cross-border e-commerce platforms: foreign terminal, tmall global, Suning cloud, Kaola and Shunfeng
the growth of new platforms mainly focuses on local cross-border e-commerce platforms, such as flipkart India, yandex Russia, tobox Russia, trade New Zealand, etc
Cross border e-commerce is based on the development of the network. The unique value standards and behavior patterns of cyberspace have a profound impact on cross-border e-commerce, making it different from the traditional way of transaction and showing its own characteristics
Transnational E-commerce has many characteristics different from the traditional trade mode, but the traditional tax system is proced under the traditional trade mode, which is bound to be full of loopholes in e-commerce trade. The network has a profound impact on human society, and also brings unprecedented impact and challenge to the tax legal norms

8. MLM must first meet the following points:
1, pay a certain fee as the entry fee, whether it is to pay or spend money to buy procts as the entry conditions
2. The most basic thing is that the income mainly comes from pulling people, not from selling procts
3. MLM can only be considered if you have to develop level 3 or above offline, and you can share the income of offline, you can also share the income of offline, you can also share the income of offline, you can also share the income of offline
Finally, it developed into pyramid model Then set up a five level three-level system, so that the boss can get out of the game with millions
you can compare this mode
9. This kind of project is generally a pyramid scheme. The spark entertainment bitcoin exposed by bitcoin house before is the best example. It is a typical project that uses software to mine and defraud money. You can check it and compare it. It is recommended to stay away from it.
