anti-theft

to prevent private key leakage

As a friendly format of wallet private key, mnemonics are very convenient for you to backup and import. Because of its plaintext, we do not recommend that it be saved electronically, but copied and kept on physical media. As a al backup, mnemonics and keystore complement each other

and keystores can be stored online, such as cloud disk, or in their own U disk (hardware wallet takes advantage of this), which is relatively safer than online storage. Even if hackers steal your keystores, they can't steal the assets without the password of the keystores, so the password of the keystores is particularly important at this time

loss prevention

the main loss prevention strategy is multiple backup, multiple backup. For example, when backing up a wallet, not only the keystore, but also the mnemonic words and private key should be backed up. This is a multiple backup

3. No, there are several reasons why bitcoin was stolen
1. A stolen bitcoin can't be retrieved, and if it's lost, it's lost.
2. Bitcoin has transaction records, but the address is hidden, and you can't find an indivial.
3. Every bitcoin has a key, and only if you have this key can you be admitted to own bitcoin. However, if bitcoin is stolen or lost, your bitcoin will disappear completely
therefore, the theft of bitcoin does not belong to cracking, it may be e to internal personnel.

4. Stolen currency and being attacked should be a headache for the exchange and it is difficult to avoid. Large exchanges usually set up their own technical team to develop the transaction payment system. Small and medium-sized exchanges can dock with third-party technical service providers, so the cost of R & D and operation and maintenance is relatively low
the exchange I am familiar with uses the currency payment enterprise version, which is a digital asset security payment system. The general principle is to store the private key locally, bind the exchange's unique client with multiple encryptions, and the system itself does not save the private key, so as to prevent the possibility of digital currency theft from the source. It is also convenient to operate, with unified management of Multi Chain and multi currency and convenient reconciliation
hope to adopt.

5. Bitcoin, Ruitai coin, Laite coin and doggy coin are real digital cryptocurrencies with irreversibility. They are a decentralized distributed network, and it is difficult to trace stolen ones. However, foreign scholars have shown that they can be traced, but they are still in the theoretical stage at present. The last time Ethernet coin was stolen, it was a hard fork solution.
