Can't bitcoin be cracked

1. 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.

2. 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.

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. Try Tencent computer housekeeper killing, physical examination speed is very fast, Trojan horse killing ability is not weak at all, for virus Trojan horse, high-risk vulnerabilities, system abnormalities will not be a mistake. Although the interface is smaller, but the function is not discounted, it is still very powerful, and the killing rate of Trojan samples in the evaluation process is 100%
the physical examination and repair of the pioneer version of computer housekeeper are very fast. It can quickly remove Trojans and fix loopholes without a long wait and has no impact on the running speed of the computer.

6. Mining software refers to bitcoin mining,
the general process is to use the computer's CPU and / or image processor to calculate bitcoin information
for Internet cafes and users, it will greatly rece computer resources:

program operation is very slow
crash
blue screen

and so on

7. As long as you fail to repay after the repayment date, you will be recorded as overe, which will generate penalty interest. The overe record will have an impact on your future loan processing in Yixin, and may be included in the credit reference system. It is suggested that you form the habit of repayment on time and protect your personal credit records.

8. Bitcoin can only be cracked by computing power, but the cost of cracking is too high. So no one is going to crack it.

9. Mobile phone poisoning may lead to online banking account being stolen, account leakage, privacy theft and other risks. If you suspect mobile phone poisoning, please install security software (e.g. Tencent mobile phone housekeeper) for one click killing
Open Tencent mobile phone Housekeeper - Security Protection (or in-depth search and kill, open Settings - stubborn Trojan horse special kill)
for system level virus, please obtain root permission to carry out in-depth clearance
Open Tencent mobile phone housekeeper (PC) - App treasure - Toolbox - one click root
if you can't handle it, please send it to the after-sales service of your mobile phone for maintenance.

10. There is no way to crack it< Data backup and recovery measures are the important work to recover the loss in the event of blackmail. It is suggested that teachers should make remote backup or cloud backup of important file data in time to prevent losses caused by virus infection
2. Make sure the firewall is on
3. Don't open unknown email or link easily.
