A cube of digital currency

1. The mainstream digital currency basically does not mention the words of international trading market. We should pay attention to this kind of trading platform, which is likely to be an unreliable platform
the mainstream digital currency trading platforms in China include five bitcoin trading platforms, as well as counterfeit currency platforms such as jucoin and bitage. Puyin also has its own special trading platform, with a trading zone in jucoin.com.

2. Buy a price and sell a price refers to the market price of the transaction order. Transaction price is the price of successful transaction. In general, the buyer will put the price is very low, the seller is relatively high. This should not be difficult to understand. Ruitai coin has a certain market depth, and there is little difference in the price between the buyer and the seller, but there is a relatively large difference between the price of Weimeng coin.

3. 1. Bithub
it is the largest digital currency trading platform in South Korea, where more than 13000 bitcoins are traded every day. This platform accounts for 50% of the Ethereum market in South Korea. Bitcoin traded every day accounts for 75% of South Korea's bitcoin market and 10% of the global bitcoin market
2. Bitmex
this is a very leading leveraged trading platform established in the Republic of Seychelles. It can operate up to 100 times leverage encryption bitcoin. But this platform needs to pay attention to that it is very suitable for experienced people to control, if you are a beginner, you must see the hidden risks< 3. Okex
okex is mainly for global currency transactions. It mainly includes not less than three kinds of digital assets, but also various derivative spot assets. Its management is a measure of separate and isolated management of various currencies. Let users have a perfect trading experience on the platform
4. Coin an
as one of the most influential digital currency trading platforms in the world, it has also disclosed financing information in recent years. That is to say, coin an is now one of the international blockchain instries that the world pays close attention to. In just 50 days of its launch, users have covered more than 180 countries around the world
5. Fire currency
fire currency is one of the three major trading platforms in China and one of the top 10 global digital currency trading platforms. Since its establishment, it has accumulated more than US $100 million in transactions, once surpassing Singapore, South Korea, Hong Kong and other teams. It provides a convenient trading platform for more than 130 countries in the world.

4. It's not necessary to say that this thing is deceitful. If it is issued by the state, there must be government and full-time personnel with certificates.

5. You have said that digital currency and RMB are 1:1 equal use, then 10 million digital currency, of course, can be converted into 10 million RMB

6. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
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

warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

To calculate the helical gear parameters, you need to know the basic parameters:

normal molus M_ n. Number of teeth Z, normal pressure angle α_ n. Helix angle β

generally, the crown height coefficient h * is 1, and the root height coefficient C * is 0.25. If there is displacement, it is necessary to calculate the displacement: x

the following is the basic parameter

end face molus: M_ t=m_ n/cos β

Calculation formula of pressure angle at the end face: Tan α_ t)=tan ( α_ t)/cos( β)

diameter of dividing circle: D = m_ n × z/cos( β)

addenm circle diameter: no displacement: Da = D + 2 × m_ n × H * with displacement: Da = D + 2 × m_ n × H * + x)

root circle diameter: no displacement: DF = D-2 × m_ n ×( H * + C *) with displacement: DF = D-2 × m_ n ×( H * + C * - x)

diameter of base circle: DB = D × cos α_ t)

in addition, there are more important dimensions, such as normal pitch, end pitch, etc., which can be obtained by referring to relevant manuals

Extended data:

judgment of helix rotation direction: first, we make the gear axis vertical, if the right height of helix is right rotation; On the contrary, the height on the left side of the helix is left-handed

end face and normal surface parameters:

end face: the plane perpendicular to the gear axis, and the parameters on the end face are generally added with subscript t

normal plane: the plane perpendicular to the helix, and the parameters on the normal plane are generally subscript n

(1) pitch and molus: = t= π

(2) pressure angle: generally, the parameters in normal plane are standard parameters

The correct meshing condition: the helix angle must be equal in size and opposite in direction. The normal molus m is equal to the normal pressure angle

B. geometric dimension calculation: in calculation, the calculation formula of spur gear can be directly applied to the end face of helical gear because a pair of helical gear transmission is equivalent to a pair of spur gear transmission on the end plane

there are many kinds of gear transmission, among which the efficiency of helical gear is very high, for example, the efficiency of spur gear transmission is lower than that of helical gear transmission

Like spur gear mechanism, helical gear can be used to improve the load capacity of transmission by recing the center distance a, which can be used for high-speed operation. Helical gear recer is a new type of recer. The helical gear recer is small in volume, light in weight and good in economy

Advantages:

(1) good meshing performance: the meshing process between helical cylindrical gears is an excessive process, and the force on the teeth is graally from small to large, and then from large to small; Helical gear is suitable for high speed and heavy load

(2) large coincidence degree: the increase of coincidence degree can improve the bearing capacity of gear. So the life of the gear is prolonged. The coincidence degree mainly depends on the meshing time, while the long meshing time and large contact area of helical gear rece the stress. The transmission is stable and the economy is increased

(3) compact structure: the less the minimum number of teeth, the more compact the structure

8. I also play digital currency through financial futures. Their operation is transparent and their service is very professional. I think it's very good.

9. I can tell you that the so-called digital currency is that the swindlers try to change the real gold and silver in your pocket into the digital currency that they say is inferior to even the Ming coin. At least the Ming coin can be seen and touched. What kind of people sell it to you!

10. There are two places from Qian Lake to Huangshan.

Qian Lake Chun'an wharf --- Huangshan scenic spot has few shuttle buses.

Qian Lake deep wharf --- Huangshan scenic spot has the same shuttle bus number as the ship, as long as there is a ship to the wharf, there will be a car to leave.
