1. This is the order of importance: BTC private key, wallet security password, BTC address
the private key is everything and must not be told to anyone
as long as there is a private key, you can re import the wallet and reset the wallet security password
a BTC account can have many addresses, so the least important one is the address. No matter how unimportant, you can't just tell others.

blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btc3. Blockchain is one of the technologies of bitcoin, which can be understood as cloud database.

5. 1. The value of bitcoin does not lie in its computing method and encryption algorithm. 2. The calculation and proction of bitcoin need time, equipment loss and electricity cost. 3. The total output of the algorithm is limited. 4. Some foreign and domestic objects have supported bitcoin payment, which makes it have the preliminary property of currency. 5. There is no difference between bitcoin and the legal currency of any country in its own value. A piece of printed paper or PVC does not have actual value. It can not have the characteristics of rare metals like gold. 6. The biggest risk of bitcoin is that no country, bank, military or government can guarantee its credibility. 7. At present, it seems to be just a virtual currency with speculation value. 8. Its circulation value is certainly not as popular as q-coin in China. For example, few people in second tier cities know about bitcoin, let alone let it admit its value.
6. Market method, cost method and income method are three kinds of mining right evaluation methods, including replacement cost method, discounted cash flow method, equivalent investment sharing method, geological factor evaluation method, joint risk exploration agreement method, etc
mining right refers to the right that the mining right holder is given to carry out a series of activities such as exploration, development and mining of mineral resources, including exploration right and mining right
exploration right refers to the right to explore mineral resources within the scope and time limit specified in the exploration license obtained according to law. The legal document of exploration right is exploration license, and its economic significance lies in: (1) transfer the exploration right according to law to obtain income
(2) obtain geological data of mineral resources through exploration work, recover exploration investment and obtain income through transferring geological exploration report
(3) as the exploration right holder has the priority to obtain the mining right, after the exploration right holder has the priority to obtain the mining right and becomes the mining right holder, he can further invest capital and technology to carry out mining, so as to obtain greater investment income
mining right refers to the right of the mining right holder to exploit mineral resources within the scope and time limit specified in the mining right license obtained in accordance with the law. The legal document of mining right is the license of mining right. Its economic significance lies in that it can mine mineral resources within the specified scope and period and obtain excess return on investment. It is a kind of franchise within a certain scope and period
market method, cost method and income method are three kinds of mining right evaluation methods, including replacement cost method, discounted cash flow method, equivalent investment sharing method, geological factor evaluation method, joint risk exploration agreement method, etc
mining right is an asset and an economic resource. The so-called assets are defined in accounting as the economic resources owned or controlled by an enterprise, which can be measured in currency and provide future economic benefits for the enterprise. According to the form of existence, assets are divided into tangible assets and intangible assets.

the appraisal of mining right refers to the appraisal of the value of exploration right and mining right assets legally transferred in the mining right market by professional institutions and personnel in accordance with national laws and regulations and asset appraisal criteria, according to specific purposes, following appraisal principles and relevant proceres, selecting appropriate value types and using scientific methods, It is the scientific evaluation and estimation of mining right assets in the form of currency in the economic activities of the mining right market. Its essence is to judge the intrinsic or potential value of the mining right (expressed as the use value of exchange value, that is, the market value). It is an estimate of the market value of the mining right based on the mineral geological information and market information, and on the basis of multi factor analysis of the present and future market
according to the definition of mining right evaluation, mining right evaluation includes eight main elements: subject, object, basis, purpose, principle, procere, value type and method< br />
