Bitcoin can be taken away

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. Obviously, the price of the spot market has changed e to the contract, but the risk of the contract is great

what is bitcoin option

the so-called bitcoin option is to predict the future rise and fall of bitcoin. In operation, if you expect to call, you will buy up and if you expect to put, you will buy down. The calculation of profit is the same as that of spot goods. When buying up, you can earn as much as you go up in the cycle. When buying down, you can earn as much as you go down in the cycle. In short, it is to use a very small principal to bet on the rise and fall space of the future range, so as to obtain a high return

how to play bitcoin options

for example, if the current price of bitcoin is $10000, you think it will rise in the next hour, so you open a one hour call option, which costs 20 usdt. As expected, bitcoin rose by US $1000 in one hour. When it matures in one hour, the system automatically settles, and you get a return of US $1000, which is 50 times that of the principal

if bitcoin falls in the next hour, you will lose the principal of 20 usdt options, which is the advantage of "unlimited return and limited risk".

3.

If you encounter bitcoin extortion email, you should first pay attention to the email title, form a good habit of reading the email title, and never open the email sent by unfamiliar people. If the unfortunate point opened, then do not follow the instructions of the swindler remittance, should immediately call the police, let the network police involved, so that we can quickly find criminals

bitcoin e-mail blackmail is really terrible, but we should calm down when we encounter bitcoin e-mail blackmail. Although this kind of blackmail fraud only exists on the network, it poses a threat to real property. We must deal with it carefully

extended information

bitcoin blackmail is a virus Trojan horse that will enter the mailbox. When users click on the email, they will find that the email page has a countdown

in fact, from the moment the email is opened, the user's computer is poisoned, and the virus has hijacked the computer. If you do not follow the prompts on the page to recharge and remit bitcoin, the computer will crash, and the data stored in the computer will be destroyed. In fact, there are many similar incidents of bitcoin blackmail, and most of the behind the scenes have been caught

4. It is recommended to use the desktop graphics card to dig faster. My Zhang account name has the group number of the learning platform

5. It's fake. Don't believe it. This is a Ponzi scheme on the Internet

6. I don't know what you mean. If you buy bitcoin on the trading platform, you can cash it into your own bitcoin wallet or sell it directly to legal tender

bitcoin is a consensus network, contributing to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network, which is controlled by its users without a central management organization or middleman. From the user's point of view, bitcoin is much like Internet cash. Bitcoin can also be regarded as the most outstanding three style bookkeeping system.

7. If you dig bitcoin in the haobtc mine, it means that it has been transferred into your account in the haobtc wallet. In this way, it can be understood that there is no difference between the normal transfer of bitcoin and the normal transfer of bitcoin. As long as you know the receiving address of the other party, click send in the account, and then enter the quantity and the receiving address of the other party to complete the transfer of bitcoin, If the other party is also a user of haobtc, you can transfer money by directly entering the mobile phone number or email of the other party's account, which is particularly convenient for you to experience.
