mining machine risk
1. The problem of electricity charge
in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
3, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
it's up to the family to dig. Large can be prepared on a host of 6 or 8 graphics cards, need rx570 (580), or gtx10610170. Then in the preparation of 20 hosts or more can make money. At least 10
the lucky chain with 100 million issued and subscription price of RMB 250 million has already completed the crowdfunding work and raised RMB 250 million
the public chain claims to be the gospel of infertile patients, which can record genes and provide a platform for assisted reproction services (IVF is a kind of assisted reproction)
this issue is only one month away from the gold chain released by Yu Lingxiong in Jeju Island, South Korea
in today's era of "talking about pyramid selling turns pale", Yu Lingxiong not only has no convergence, but has become the "father of pyramid selling" anyway. With the help of blockchain, he has bred pyramid selling coins like locusts.
he used to be a junior high school graate, a blacklisted veteran in the court, and a loser in people's eyes... Now, he has adopted the blockchain outlet, but he has become a respected teacher among the people.
hope to adopt
BVI company cooperates with Singapore foundation for al structure information confidentiality
how to legally operate the ICO issue has always been the focus of attention of people in the instry
today we will talk about the concept of al structure of BVI company and Singapore foundation. In fact, the al structure is not new to many people, But in fact, many people may not be familiar with the project development applied to the ICO field.
first of all, let me talk about BVI company in the al structure
Introction to BVI company
as we all know, BVI is one of the overseas offshore investment centers with the fastest development of 9370 and 6165 in the world, and the company registered here is called BVI company, It is commonly used in the vie trading framework for listing overseas or in Hong Kong. According to the law of the island, all companies incorporated in the island are exempt from tax except for the statutory annual registration fee (very small). Many well-known international companies set up tax avoidance companies in the island for their tax avoidance operations, and carry out complex international tax avoidance business activities. The information is confidential. It is one of the preferred architectures for the majority of investors.
{rrrrrrr}
the basic way to build the compliance architecture is as follows:
1. Register BVI, as the issuing entity, keep personal identity information confidential, and completely avoid taxes.
2. Set up the Singapore Foundation (CLG), as the project operator, to legally operate blockchain projects and digital currency operations
3. Only the promotion and technical teams are reserved in China, which are clean and compliant with the operation and distribution
legal compliance of compliance framework:
1 legal opinion: (white paper compliance + token uncertified certificate)
legal opinion issued by lawyers to determine whether the tokens issued by the project comply with the relevant laws and regulations of the monetary authority of Singapore (MAS), especially the white paper project with al currency, needs to be strictly reviewed by lawyers
2 government compliance endorsement: issue official endorsement to further enhance project compliance (provided that a legal opinion has been issued)
3 Singapore sto compliance: assets with certificate attributes To facilitate compliance and issuance under the current sto management guidelines in Singapore, the following proceres are needed:
1 to register BVI company
2 to register Singapore foundation
3 to issue Singapore legal opinion
4 to issue ICO
the project party registers a limited liability company in BVI and claims that the main body of the foundation is BVI company. Then we set up a public welfare foundation (CLG) in Singapore. BVI company cooperates, authorizes and operates ICO related projects. Of course, each currency needs an independent foundation to operate, so as to avoid the risk of currency trading on the foundation body. Finally, Singapore commonweal foundation authorized domestic marketing team and technology R & D team to carry out project promotion and technology R & D
