Can BTC wallet be cracked

1. After the ZF policy, the domestic bitcoin exchanges were basically closed on October 31. Therefore, if bitcoin wants to be realized, it can only be traded on the OTC exchanges of bitcoin abroad. Many of these closed platforms have opened OTC exchanges abroad, but I don't use much. I only use the coinbee platform and sell a few coins. This is how his OTC trades, The basic routines are the same. First you have to register your account, then get your wallet address from the coinbee platform, then recharge the bitcoin into it, choose to publish advertisements, choose the quantity, price, acceptable transfer method, such as Alipay or bank transfer, if someone wants to buy your currency, he will Send a transaction request to you. Then you trust bitcoin, wait for him to call you, and click on the platform to complete the payment. After you confirm that you have received the payment, you can click release bitcoin on the platform to complete the transaction. This is my actual operation. There will be risks. Be careful. This is my personal practice, and I hope it will be useful to the subject.
2. It depends on your ability to crack people. People with high ability may take only a few minutes.
3. I forgot my private key, but I can't solve it
4. 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.

5. First of all, let's talk about the background. The basic principle of bitcoin "account" is key public key address. You can roughly understand it as "key box box number". Now is to start from the box number or box to crack the key
there are basically two kinds of attacks, one is dictionary attack, the other is brute force attack
dictionary attack is to use common passwords and their simple variants as keys one by one. As long as your pass phrase is not hard enough, the possibility of successful attack is very high. So if you want to use this, you need to popularize the knowledge of cryptography first, and don't think it's very safe to add a long password
if you don't use the wallet generated by pass phrase, you can only crack it violently, which is equivalent to enumerating all the possible keys. At present, this is impossible, even if the electronic computer is becoming more and more powerful. However, quantum computer can do it theoretically, but don't worry too much. If such a powerful quantum computer comes out, it will not only endanger bitcoin
at the same time, bitcoin has a second layer of protection: if an address only accepts bitcoin but does not output it, its public key is confidential, that is to say, no one else can see the box, only the box number. At present, the process of decing the box from the box number can't even be done by quantum computer. In other words, if there is a quantum computer, bitcoin has a last line of Defense: it's temporarily safe to transfer your money to a new address
finally, some time ago, the wallet generated by the Android client was attacked because of a bug in the underlying random number generator. In fact, this function is not random securerandom, which Google quickly admitted and fixed. It's hard to say whether this kind of thing will happen again, but I don't think we need to worry too much.

6. Common measures to deal with the loss of private key and password:
1. Delete the wallet by mistake
this is the same operation as I do. What should I do in case of this kind of thing? In fact, as long as you remember the private key, download a wallet again, import the private key and reset the password of the wallet
2. The mobile phone is missing or broken
if your mobile phone is stolen or broken, as long as the private key or mnemonic word is still there, you can download a wallet again, import the private key (or mnemonic word) and recreate the wallet
3. The private key is forgotten, but the mnemonic (or JSON file) is still there
if your private key is lost, but the mnemonic (or JSON file) is still there, don't worry, mnemonic can help you retrieve the private key,
4. The private key is forgotten
the wallet hasn't been deleted. If your private key is forgotten, but the wallet is still on your mobile phone, it's very easy to do, You just log in with your password, enter your wallet, and back up your private key
5. The private key, password and mnemonic words have been lost
sorry, no one can help you
6. Forgotten password or wrong input
this is the same as some other apps that we usually log in. If we forget password or input error several times, click forget password to retrieve it. Back to the decentralized wallet, we need to use the private key or mnemonic words to import the wallet to reset the password
7. Forget the mnemonic words
import the wallet with the private key and back it up again
8. Keystore forgotten
if your wallet is not deleted, this is the same way as if your private key is forgotten but your wallet is not deleted, that is, log in with your wallet password and make a new backup; But if your wallet is deleted, that is, it is unloaded, you need to import the wallet with mnemonic words or private key to backup the keystore again!

7. If you use brute force to crack the wallet, you must remember the password phrases you used, for example, I must have used ABC, I may have used 321, and so on. If the wallet address is not yours, you can't crack it even if you use up the energy of the sun. Regular company can come to sign an agreement to crack the service.
8. The essence of BTC is a distributed, algorithm-based and public network account book (just as the essence of a bank is a private account book which is not publicly controlled by the central government). The wallet (private key) is actually the right for you to modify the account number (public key or bitcoin address) in the account book. The wallet corresponds to the account number. In fact, the specific wallet file contains more than one private key information, which can be copied to other places for use. As long as you have the private key corresponding to the account, it's like having the password of the bank card. Understand the above, you should also understand the answer to your question - B has 10btc on the address. It's not about the computer. This may be better understood by you: wallet = private key (bank card password) + public key (bank card number) BTC network system = Bank, access to BTC network with wallet = bank card inserted into ATM and certified, payment = transfer to other accounts.
9. How to choose BTC wallet and how to store your bitcoin? This is an important problem that every bitcoin user must face. Bitcoin gives you more freedom and power to control your money. But if you are not careful, it may bring disastrous losses. If you choose to remain in complete control of your bitcoin on your own, then there is no one who can stop you from doing something stupid and pay for your mistakes. There is no bitcoin company to call and try to convince your legitimate owner of your address so they can give you the key back. However, there are friendly and secure services based on bitcoin, or intermediate solutions, which can let users avoid the risk of operating wallets. The purpose of this article is to explain what different options you have for storing BTC, so that each user can make the right choice between security and control. Wallets fall into two main categories: Online wallets online wallets are by far the easiest way to access your bitcoin from any computer. But there needs to be enough trust in wallet service providers. Currently, there are four main choices for online Wallet:
