How long does it take for digital currency to mention wallet

1. No, it only needs the currency supported by the wallet. If the currency not supported by the wallet is transferred in, the coin will be lost. The charging address of each coin is different. Moreover, the wallet is a small platform. I feel that it is not as safe as ZB, but some personal wallets can be used with some amount

2. In order to make it more convenient for us to use money now, and in other words, to facilitate the circulation of money.

3.

in terms of cloth storage and mining, I recommend Heshu hardware wallet and jiajiabao intelligent home miner. The core advantage of the proct is safety

take sum hardware wallet as an example. The advantages of sum hardware wallet are as follows:

1. The private key seed is encrypted layer by layer, physically isolated and never touched the Internet.

firstly, when creating the wallet, the seed password is generated and stored in the local encryption chip, and the 10 bit payment password is required

then, the transaction is made in the wallet. At this time, the user needs to enter the payment password to obtain the private key to digitally sign the transaction, and the transaction is completed. In addition, the private key seed is permanently stored in the chip, which is physically isolated and never touches the Internet. There is no need to worry about my password being stolen by hackers

Second, the bank system verifies the financial level motherboard and encryption chip

uses the bank system to verify the financial level motherboard, and the private key seed is stored in the chip. If the proct is stolen or lost, and destroyed by malicious violence, the chip will trigger a self destruct circuit, and immediately permanently and irrecoverably delete all the information in the area

Third, it supports the withdrawal of global bitcoin ATM, which is convenient and fast

the reason why digital assets attract the attention of many fields in the world is that it is creating a global fast circulation, and the larger the circulation field is, the wider the scope is, and the higher its use value is. The core of digital assets is the medium it acts on among currencies. The Heshu wallet has built-in many mainstream exchanges in the world. It can trade digital assets anytime and anywhere. With one machine in hand, it can walk around the world without worry, and no longer have to worry about exchanging foreign currency

Different from conventional digital wallets, multi signature wallets need the authorization of multiple key holders to transfer digital currency, so the security of multi signature wallets is higher. Ordinary Wallet: a wants to transfer a bitcoin to X. A only needs his signature (using the private key) to complete the transaction. Sum Wallet: if a wants to transfer a bitcoin to x, a multi signature verification is set (at least two signatures of Abc3 indivials are required to transfer the money), then a needs B or C to complete the signature (using the private key) when a wants to transfer the money to X. I hope I can help you. Thank you

The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods

many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat

extended information:

whether the hardware wallet is safe

the hardware wallet can not guarantee 100% security. For example, if a geek obtains your hardware wallet, it may be cracked violently even if it doesn't know your hardware wallet immediately. It's just one of the safest storage methods compared to other storage methods

of course, there are exceptions, such as you have unlimited brain power and never forget. It's better to save it anywhere than in your own mind

5. The answer is yes
when transferring money, the receiver only needs to send the address of the wallet to the other party, and the other party can transfer the digital currency to the address. When trading in the exchange, the user should also enter the digital currency into the address designated by the exchange, that is, the wallet, to complete the transaction. At the time of withdrawal, the exchange will also enter the digital currency into the user's wallet address accordingly. This is how the money should be transferred to the wallet.

6. It's a tool for managing and using digital currency.

7. How about setting the balance of the money b account in the money wallet? Transfer to the OTC account, which generally requires an exchange rate settlement or a conversion

8. Safe and reliable digital wallet should be designed from at least five dimensions:
1. Security risk of running environment
the core file of encrypted digital currency Wallet - private key / mnemonics is stored on the terminal device, whether it is PC or mobile terminal, if the terminal device appears unsafe phenomenon, it has a very high security risk for private key / mnemonics
at the beginning of design, a secure digital wallet can avoid the possibility of private key / mnemonics being stolen e to the running environment. The security problems of the running environment on the terminal mainly include virus software, operating system vulnerabilities and hardware vulnerabilities
2. The security risk of network transmission
the security of network transmission is more reflected in the ability to resist man in the middle attack. Man in the middle attack means that the attacker creates independent contact with both ends of the communication and exchanges the data they receive, so that both ends of the communication think that they are talking directly with each other through a private connection, but in fact the whole conversation is completely controlled by the attacker
although most digital wallet applications use the HTTPS protocol to communicate with the server, the man in the middle attack method is to get the content of the HTTPS protocol by installing a digital certificate in the user terminal
a secure digital wallet needs to be able to scan the legality of all the digital certificates in the terminal, check the proxy settings in the network transmission process, and ensure the security of the basic network communication environment
in the development of digital wallet, whether to use two-way verification for communication verification at the network transmission level is also an important criterion to measure the security of a digital wallet application
3. The security risk of file storage mode
for the private key / mnemonics of digital wallet, the storage mode of terminal device also needs to be paid attention to in the security design. The access right of private key / mnemonic file directory, the form of private key / mnemonic file storage and the design of encryption algorithm all need to be strictly designed
when we analyze the security of several mainstream digital wallets, we find that even the well-known digital wallets are random in the storage of private key / mnemonic words. There are both plaintext storage and encrypted storage, but the decryption key is fixed in the code, which can not play any role in security defense
4. The security risk of the application itself
the security risk of the application itself mainly focuses on the security defense of the application installation package itself
whether the application installation package has the ability of anti tampering is a very core technical ability. In addition, memory security, anti debugging ability, life cycle management of private key / mnemonics, security of debugging log and security of development process also need to be enhanced
5. Security risk of data backup
if the mobile application can be backed up, it can use the machine with more powerful computing performance to brutally crack the private key / mnemonics. For example, if android:allowBackup Property is set to allow backup, then the backup mechanism of the system can be used to back up the application data files, and the private key / mnemonics of the encrypted digital currency will be backed up to the external media, which breaks the security boundary design of the operating system from another direction
for the majority of users, the security of digital wallet also means the security of wealth, so we must be careful when choosing digital wallet.
