Bitcoin cracking time

1. It depends on your ability to crack people. People with high ability may take only a few minutes.
2. 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.

3. Caibi tix is good. It can be said that caibi tix is the first potential virtual currency in 2018. Many people buy it, and its appreciation is fast.
4. Theoretically, it can be cracked, but it's just a time-consuming problem. If you think about the cost of mining, you should know the difficulty of cracking. To protect bitcoin by means of encryption must make the cracker pay a much higher price than mining, otherwise everyone can get it by cracking rather than mining
5. Unknown_Error
6. You can prevent bitcoin virus by downloading more windows updates
and opening the firewall
or downloading antivirus software
effectively

7. You can use 360 or computer housekeeper to crack it. You only know that the computer housekeeper needs to crack it within three days of poisoning. Otherwise, there is almost no cure
