Chain only ICO blockchain
ICO trading is roughly divided into two parts, one is OTC trading, the other is exchange trading. There are three ways to go to the exchange, the first is to vote on the currency, the second is to invest in the currency, and the third is to cooperate with the project party
for the exchange, the more platform coins consumed by voting, the better; For the project side, the lower the cost, the greater the impact of users, the better; But for ordinary social users, the easier it is, the better
What does the project party need to have
{rrrrrrr}
the cost of project docking with the exchange:
at present, the popular Matcha exchange generally has about 12-15 BTCs,
biki and gate exchange have about 10 BTCs,
ZG exchange has many choices when docking with 6-8 BTCs,
2-5 BTCs, such as Lein, ZBG, fcoin, WBF and so on
Fcoin, which is relatively cost-effective, is also a good choice. Later, the project parties can work together with the platform to do activities, whether it is airdrop, IEO or other can be discussedblockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.
the underlying technology of blockchain bitcoin is actually that it supports the stability of bitcoin in the past eight years. You can understand it as a subversive accounting method or database, and the core is decentralization
ICO, which is essentially blockchain crowdfunding. If an enterprise does ICO, you can understand it as IPO, But the financing is not money, but virtual currency, such as 3000 bitcoins. Of course, you can choose to sell it in any country in exchange for the legal tender of a country
Recently, there are three popular concepts: blockchain, bitcoin and ICO
one is the blockchain, which is the blockchain in Xu Xiaoping's internal letter that "if it goes along, it will prosper, if it goes against, it will die"
the other is that it has been hyped for several years, and the price keeps going up and down, but some people have been advocating bitcoin that "each bitcoin will rise to $10000"
Another is the ICO, which Xue Manzi cheered and advocated a few months ago and later was strongly concerned by the regulatory authorities. On the night of January 12, the day before yesterday, the China Internet Finance Association issued an announcement entitled "risk tips on preventing disguised ICO activities", in which it named the digital currency "chain gram" (formerly "play guest currency") released by Xunlei, saying that it "replaces the legal currency payment obligation for the services contributed by the participants, which is essentially a financing behavior and a disguised ICO". As soon as the news came out, Xunlei's share price fell sharply in the early trading of us time on Friday 
"bitcoin" does not solve any problems
besides bitcoin, Xiaotao has always been a loser of bitcoin, because in Xiaotao's view, bitcoin has not solved any new problems. In other words, what would the world lose without bitcoin today? Who and which transactions will be affected? The answer is that no one will be affected except the most special people. What are the advantages of bitcoin over existing currencies? Stable currency? Security? Low cost
the decentralization advocated by bitcoin is nothing more than evading regulation. For example, the goods between the two countries should have gone through the customs. The Customs has eight channels. Now you have an underground channel. Although the distance may be closer and many customs ties may be exempted, it is illegal. It is a typical Arbitrage Behavior to evade supervision. Solving one's own problems on the premise of harming social interests and order is not desirable and can not last
What's more, in order to obtain bitcoin, the huge "mining" workload consumed a lot of power and computer computing power, and did not create any value, which is a huge waste of social resources. It is said that the cost of digging a bitcoin has reached 3000 to 4000 US dollars...
"ICO" is a typical Ponzi scheme
as for ICO, the so-called IPO project with digital currency as the media, sticking to its own hot speculation concept, holding the idea that it is not ready to cash, or the idea that the feasibility is almost invisible, relies on a kind of digital currency that evades the supervision to let people buy and hype the price... This is a typical Ponzi scheme, or open a casino in disguise
there are many such cases in history. A few years ago, some people divided any painting into tens of thousands of shares, marked a price for everyone to buy and hype; Hundreds of years ago, the Dutch were crazy about tulips. A tulip price could buy a castle... Everyone knew that it was a bubble. They all knew that the bubble would burst, but everyone wanted to beggar the neighbour, hoping to get a.
before the bubble burst.there are three types:
1. If an employee inquires and prints his / her detailed insurance information, he / she needs to provide the original ID card and the original social security card (check the original and take back the photo); If an employee entrusts others to inquire about his / her insurance information, he / she shall provide the original of the power of attorney, the original of the client's ID card, the original of the client's social security card and the original of the trustee's ID card (except for the original of the power of attorney, the original of other materials shall be checked and photocopies shall be collected)
2. If the company inquires and prints the personal insurance information of its employees, it is necessary to provide the inquiry proof materials with the official seal of the company and the original ID card of the operator (the original proof materials, the original ID card and the photo shall be received)
3. Querying and printing the detailed list of indivial insurance is a free business
therefore, enterprises sometimes mention that printing enterprise payment details is actually printing payment notice; In the system, the enterprise can not see the details of the payment to a specific employee. If you want to know, you can enter the ID number of the employee in the social security center to inquire, or the employee will log in to the Tianjin city's human resources or social security net to inquire. Basic medical insurance is a social insurance system established to compensate workers for the economic losses caused by disease risks. Through the payment of employers and indivials, the medical insurance fund is established. After the medical expenses of the insured are incurred, the medical insurance agency will give certain economic compensation, so as to avoid or rece the economic risks caused by the illness and treatment of workers
basic medical insurance is one of the most important types of insurance in the social insurance system, which, together with basic endowment insurance, work-related injury insurance, unemployment insurance and maternity insurance, constitutes a modern social insurance system
on May 1, 2016, provinces (autonomous regions and municipalities) that have paid more than 20% of the basic endowment insurance for enterprise employees will rece the payment ratio to 20%
provinces (autonomous regions and municipalities) with 20% of the unit contribution and more than 9 months of the accumulated balance of the basic endowment insurance fund for enterprise employees at the end of 2015 can rece the unit contribution to 19% in stages, and the period for recing the rate is temporarily two years. The specific plan is determined by each province (region, city)

however, in the coin circle, it is important to use bitcoin ICO, and then the platform will send some tokens to users. However, the price fluctuation of these tokens is very large. Now the profit possibility of this model is relatively small. Another is the European crowdfunding model. Crowdfunding projects issue tokens, which exist as asset certificates and have a fixed dividend mechanism.
vechain platform is a global ledger information interaction and cooperation cloud platform based on blockchain technology. Through the docking of API and application layer, people, things or things in the real world can be digitized to realize the interconnection of information. Through the intelligent contract based on the practical application of the instry, the collaboration and value transfer in different scenarios are realized, so as to map the real business world to the blockchain. Through the cross platform, cross enterprise, cross instry and cross-border Internet cooperation, we can create a new business model and provide "trust service" for the cooperation participants
the source code base of ONLINK comes from Ethereum. In order to facilitate business applications, it has made a lot of improvements in dynamic protocols, smart contracts and other aspects, and is committed to applying blockchain technology to build a trusted distributed business ecological environment that can not only self cycle, but also expand outwards: information is relatively transparent and symmetrical; The trust friction among different participants is minimized; Different participants display their own strengths and contribute their own value to the business ecological environment, so as to obtain relatively fair remuneration; Realize the value of high-speed flow, and continue to expand the chain only business closed-loop< 2. Functions of vechain platform: the token used in vechain is ven, which is the ecological blood of vechain platform, and each participant can obtain corresponding procts and services by paying ven:
1. End users and ecological enterprises, as investors, pay eth at the beginning to obtain vechain token (ven), Eth has handed over the platform to Weilian foundation for technology development, promotion of commercial application cooperation, and support of blockchain services
2. Weilian foundation collects ven from the development and service providers of various smart contracts, and pays the gas required for the operation of smart contracts to ensure the operation of various business intelligence contracts; 75% ～ 99% of the revenue collected from ven will be used as node reward and paid to the node provider, while the rest will be used for the subsequent daily operation, commercial promotion and technology development of Weilian foundation
3. Smart contract service providers pay ven to obtain gas, provide baas (blockchain as a service) smart contract services for the enterprises they serve, and collect ven from their customer enterprise application development providers to provide smart contract services according to their respective business rules and added value contributions
4. According to the needs of the end-user enterprises, application development providers carry out further development and processing on the basis of smart contract services, provide application procts for their traditional enterprise customers or end-users, and charge ven as enterprise income
5. End users can pay ven to obtain enterprise procts and services< Third, the distribution of Ven
ven is expected to sell 410 million vechain token (ven) from 20:00 on August 18, 2017 to the end of August 31, 2017. ICO participates by raising eth, with a minimum trading volume of 0.01 eth, and will be issued as ven at the ratio of 1:1 on September 20, 2017. Participating in ICO before 20:00 on August 21, 2017 can get an additional 15% ven award, that is, 1 eth = 4025 ven; From this time to the end of crowdfunding, participate in ICO, and the exchange ratio is 1 eth = 3500 ven.
