Can you dig virtual currency without wallet

1. Reason: with the rapid development of information technology, real money is far from meeting people's demand for capital flow. If there are enough people to recognize the value of a virtual currency, it may become a substitute unit of material exchange, and the existence of virtual currency will inevitably cause another upsurge in the financial sector
in view of the possible risks of virtual currency, many international organizations and central banks have responded publicly to the supervision of virtual currency system. These responses can be roughly divided into four categories: warning and risk warning, supervision and registration permission, legislative norms, and explicit prohibition
(1) warning and risk warning
some central banks and regulators have issued risk warnings against the special currency and virtual currency system. The federal financial regulatory authority of Germany, the Bank of France, the central banks of the Netherlands and Belgium have issued public warnings against the possible money laundering and terrorist financing caused by the use of bitcoin. In the report released at the end of 2013, the European Banking authority (EBA) warned consumers of many risks of virtual currency, such as exchange loss, e-wallet theft, unprotected payment, price fluctuation and so on. Although Spain did not have a similar risk warning, it issued a timely information announcement related to virtual currency
(2) supervision and registration license
generally speaking, international organizations believe that the supervision of virtual currency should find a balance between risk prevention and innovation promotion. Since 2012, Sweden has required transactions related to virtual currency to be registered with financial regulators. Other countries pay attention to qualification supervision, so as to make it indirectly meet the requirements of prudential supervision. In other countries, the regulation mainly focuses on the business model of virtual currency transaction. The financial prudential regulatory authority of France regards the provision of bitcoin circulation and trading services and the act of earning funds in the process as a payment service and requires the authorization of the government. In addition, some countries focus on the intermediary institutions related to virtual currency. The German federal financial regulatory agency and Danish regulators believe that the provision of intermediary services for virtual currency needs to be authorized< (3) legislative norms
at present, some countries have proposed legislation to regulate virtual currency transactions. Canada plans to legislate to allow the government to supervise the transaction of bitcoin, and to include the transaction of more than US $10000 into the scope of suspicious supervision. The United States hopes to adjust the relevant legal structure should be compared with the development of the special currency. In order to make the Bank Secrecy Act (BSA) applicable in the context of network, the financial crime enforcement network (FinCEN) of the U.S. Department of the Treasury issued the explanatory guidance on the behavior and subject definition of private generation, holding, distribution, trading, acceptance and transmission of virtual currency in 2013. The European central bank stressed that it should strengthen international cooperation under the existing legal framework, and regulate virtual currency from the European and global level under the existing legal framework. More countries believe that bitcoin is not a currency in circulation, has no legal status, and does not meet the definition of financial instruments, such as Finland, Sweden, Malaysia and Indonesia
(4) it is forbidden
in some countries, bitcoin related transactions are prohibited. In December 2013, the people's Bank of China banned financial institutions from trading in bitcoin, which was subsequently extended to payment service providers. The central banks of Thailand and Indonesia share the same attitude. The circulation of anonymous internet currency (including bitcoin) is prohibited by the Russian judicial inspection department as a substitute for currency. The Central Bank of Russia has earlier included the provision of bitcoin services in the scope of suspicious transaction monitoring. The U.S. Securities and Exchange Commission (SEC) has banned the issue of unregistered shares in exchange for bitcoin, and unregistered online securities trading activities in virtual currency.

Virtual currency wallets and local wallets are wallets specially used to store virtual currency

difference: local wallets are installed on their own computers or mobile phones, while online wallets encrypt the private key and put it on the server

personal computers may be implanted with Trojans; The wallet server also has the risk of being attacked by hackers, and the encrypted private key is cracked. Server security is better than personal computers, but it is easier to attract hackers' attention

< H2 > extended data:

virtual currency Wallet:

there are three main types: Online wallet, client wallet (mobile client, computer client) and hard wallet

1. Online Wallet: it refers to the operation of virtual currency relative to wallet by users in the form of network; The main form is website, which users can visit through computer and mobile phone

2. Client Wallet: it is an installation software, which needs to be downloaded to the computer or mobile phone, and can only be used after installation; This is the type of mobile app wallet that I just mentioned

3. Hard Wallet: it is similar to the wallet in the form of U disk, which is a real type of wallet

local Wallet:

the English name of local wallet is local wallet. Local wallet is to store private key and transaction data in local terminal, such as computer, mobile phone or other local devices; It refers to the storage location of the key, and its concept is independent of online wallet and offline wallet

the English name of local wallet is local wallet. It is one of the terms related to bitcoin wallet in blockchain. Local wallet is to store private key and transaction data in local terminal, such as computer, mobile phone or other local devices; Local wallet refers to the storage location of key, which is independent of online wallet and offline wallet

the local wallet is installed on your own computer or mobile phone, while the online wallet is encrypted and put on the server. Personal computers may be implanted with Trojans. Hackers may steal your wallet files and record your wallet password; The wallet server may also be attacked by hackers, and the encrypted private key may be cracked. Server security protection is better than personal computers, but it is also easier to attract hackers' attention. In terms of security, I think these two types of wallets are similar

to enhance the security of local wallet and online wallet, it's better to set a more complex password, and don't forget it. Both local wallet and online wallet are easy to use and easy to use. Because online wallet is not limited by clients, it is easier to use than local wallet. Bitcoin core, Bitai wallet and bitpai wallet all belong to this category

No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

4. Different virtual coins have different digging methods
coins with pow algorithm like bitcoin need professional miner to dig, that is to say, you need to buy miner first
as long as you hold the coin in your wallet as required, you can get extra token rewards
some dpos currencies, such as EOS, only super nodes can get rewards, but ordinary users can get rewards through pledge.

5. This is done intentionally by the platform. If the coins are mined by users' wallets, there will be less money in the hands of the platform. Users may throw money at any time, and the cost of the platform to raise the price will naturally increase. This is not what the operators of platform and Shanzhai coin want to see. The plates of these coins are generally small, and users will subscribe for some of them
however, it is recommended that users invest in bitcoin, Ruitai coin and Laite coin, which are digital cryptocurrencies with market depth, and the risk is relatively small. For other Shanzhai coins without market depth, the platform may run away at any time, and users may become disk takers at any time.
