Is bitcoin account safe
bitcoin is very risky. Although bitcoin can be used for real commodity transactions, there are still many restrictions, so its use value is limited
moreover, bitcoin has certain political and legal risks. If bitcoin is prohibited by law in the future, the money you invest in bitcoin may be wasted
in addition, the security of the platform is also very poor, and there are great risks in the storage and trading of bitcoin. After all, bitcoin only depends on source code to store, so once stolen, it is basically irreparable. Many trading platforms have been attacked by hackers and lost a lot of bitcoin
the quantity of bitcoin is also limited, and it is vulnerable to price fluctuations. Its highly volatile exchange rate just shows its instability. After all, it lacks a strong financial system to support it.
Bitcoin is a kind of encrypted digital asset protected by cryptography, without the participation of centralized institutions. It has been running steadily since 2009 and has become one of the important investment targets of global investors. Many investors are very interested in bitcoin investment. The entry process of bitcoin and some investment procts is slightly different. The address of bitcoin blockchain is decentralized, so there is no account opening step. However, purchasing Mai bitcoin with bitcoin requires the assistance of some third-party platforms
at present, there are relatively large platforms in China, such as okex, fire coin and coin security. I have been in and out of money for many times in these platforms. Let's introce my experience of buying Mai bitcoin in these exchanges.
before the introction, I need to explain one premise: the security of Mai bitcoin is divided into two aspects: one is asset security, which basically won't cause any problems when I choose the three major domestic exchanges; the other is capital security, in other words, Is to rece as much as possible with the flow of black money bank card transactions. Because it's easy to freeze their bank cards, each exchange has a different strategy
1、OKEx： https://www.okex.me/buy-crypto/cny
okex is the exchange that I use the most Mai currency. I have been in okexmai currency since 18 years. Most of the time, I have had a good experience of Mai currency. I only encountered the problem of freezing okex account (not bank card freezing) once in my impression. However, OK customer service also helped me understand the freezing process very quickly. This is my first contact with OK customer service, Good attitude and high efficiency< it can be seen from the side that okex has done a lot of work in the prevention and control of black money. Moreover, in recent years, there are few card freezing incidents in okex. Today, the black money in the exchange is increasingly rampant, okex has done quite well
in terms of user experience, the function of one click Mai is more suitable for Xiao. When using this function, you don't need to select the businesses that meet the standard in the list of businesses. It's more convenient. At present, when you do activities, you will get a 20 yuan reward when you buy Mai for the first time
in addition, okex is a first-line exchange with a large user base. Mai currency supports wechat, and ZFB buys Mai with zero handling charge. If you've just come into contact with bitcoin, it's a quick and safe choice in okexmai
However, the weakness is that okex has little support for foreign currencies. Except for RMB, only the Vietnamese Dong and Indian Rupee have depth. The Mai currency entrance of other countries' currencies is only the interface of other cooperation platforms2 https://www.huobi.com/zh-cn/
the exchange's legal currency trading plate is deep enough, and there are many powerful businesses with good experience. Support the purchase of Mai bitcoin with multi currency. In addition, the process of making Mai coins is relatively smooth and can be completed in a few minutes
however, e to the good user experience of fire coin, black and gray procts will also choose fire coin as a channel for money laundering. fire coin has been updating its risk control strategy to intercept black money accounts. However, at present, it seems that the effect may not be so good, and the freezing card incident continues. Friends who pay close attention to the digital money market may understand that a large-scale freeze occurred in early June, and many users' bank cards were frozen. Therefore, we should be a little more cautious when using Mai coins on this platform, try to choose the ranked merchants, and rece the probability of being frozen.

the trading plate of currency security legal currency started late, and the accumulation was not enough. Frankly speaking, the depth and experience of legal currency trading is quite different from that of okex and fire currency< Strong>, especially the t+1 strategy of currency, which is Mai currency, will make complaints about money in a day. This system has been thrown into the trap by too many people, because this is obviously a "one size fits all" strategy with insufficient technical capability.
however, even if there are many slots, coin an is slightly better than the second and third tier exchanges in terms of asset security. Users who trade in coin an can also try to buy Mai bitcoin in coin an
finally, based on the above factors, it is suggested that okex is the first choice for Mai bitcoin, fire coin is the second choice, and coin security is not recommended
If bitcoin accounts are decentralized, so are hackers. Bitcoin, which uses blockchain technology, is not more secure than bank accounts. On the contrary, it is vulnerable to hackers. So, in the world of virtual currency, how to protect the security of account funds
Secret your private key address
the bitcoin address is the only information needed to define the distribution and transmission end of bitcoin. These addresses are generated anonymously by the user's wallet. Once the address is used, all the transaction history related to it will destroy the confidentiality of the address. Anyone can view the balance and all transactions at any address. Because users usually need to disclose their identity in order to receive services or goods, the bitcoin address cannot be completely anonymous. For these reasons, it is better to use bitcoin address only once, and users must be careful not to disclose the address
When replacing the computer, try to destroy the hard disk of the original computer. Don't save or publish the private key of bitcoin to the cloud, mailbox or collection. If a network administrator writes a regular expression to retrieve the text, he can find all the information and crack the user's account2. Stored in bitcoin wallet
many bitcoin exchanges have been attacked by hackers. If you use the wallet of bitcoin exchange, please use Google's "double authentication" to ensure security. During the development of virtual currency, there have been many cases of bitcoin exchange running away. The exchange owns the private key of the user's wallet, which is not a safe way to save bitcoin
bitcoin wallet has a wide range of customers, which is more secure than the wallet service of bitcoin exchange. No matter what kind of wallet you choose, you should choose a strong password. Don't use the same password as the registered email. At the same time, do not put eggs in the same basket, choose multiple storage ways to improve the security of assets
using the genuine system of bitcoin wallet, regularly updating security vulnerabilities and fixing bugs can improve security. Some studies have pointed out that IOS system is more secure than Android system, because the existing security vulnerabilities of Android system may be relatively easy to be attacked by hackers
3. The most common way to identify phishing sites is phishing sites. Hackers will create a domain name similar to bitcoin website, which may be sent to users through e-mail and other channels. Once users try to log on the website, hackers will record their login information
so be careful before clicking any link. Many browsers have the service of "phishing check". If you carefully identify the domain name of the website, you can identify the phishing website
4. Guard against Keylogger
in addition to phishing sites, the common attack method of hackers is Keylogger. Keyboarding is the easiest way to capture passwords. The deception of key recording software is very high, even the technical house may believe it. In short, a keyboard recorder is actually a script code. Once it is installed on the operating system of the target computer, it will record all the keystrokes on the keyboard and send them to hackers, mostly through FTP
the successful method of introcing Keylogger depends on many factors, including the operating system, the lifetime of keylogger and the anti infection level of target computer. Keyboard recorder is usually injected through web browser. The security vulnerability of the target machine depends on the type of browser it uses; Whether the operating system installed on the target machine is genuine, and whether the operating system is updated with the latest security vulnerabilities and bug fixes
5. Watch out for USB theft program
the software will retrieve your password and login credentials stored in the browser. Once FUD, some stealing programs can be very powerful. In most cases, a steal program is a. Bat file, which can be injected into the target machine online or driven by USB
6. Using proxy and VPN
proxy server and VPN can increase the security of your bitcoin wallet, although most people mistakenly believe that VPN makes them anonymous online. But in fact, VPN only improves the privacy of users. VPN can rece the possibility of hackers accessing the router to open the port, which also means that they are less likely to succeed
7. Encryption and backup wallet
wallet backup is essential to prevent losses caused by computer failure or human error. If a computer or mobile phone is lost, a backup wallet can help retrieve the bitcoin. At the same time to encrypt the online backup, any backup that can be accessed through the Internet should be encrypted
how to back up your wallet? First, close the bitcoin client, then select the backup wallet of the menu file in the main interface, and the wallet.dat file to other hard disk partition, mobile hard disk or U disk
it should be noted that the entire wallet should be backed up, not just the private key. Bitcoin wallet has many private keys for receiving transaction change. If only the private keys of visible bitcoin addresses are backed up, most of the funds may not be restored from the backup. Also, back up your wallet regularly to make sure that all recent bitcoin change addresses and newly created bitcoin addresses are included in the backup
Cold storageoffline wallet is called "cold storage", which is the safest way to save digital currency
cold storage is an offline wallet that is not connected to the network, that is, it will not be attacked by black horse and Trojan horse. However, because the operation is relatively complex and the price is relatively expensive, the price of offline wallet is more than 1000 yuan, which is suitable for users who have a lot of bitcoin and are ready to hold it for a long time
although the operation of cold storage is relatively complex, it is the safest storage method. At present, only cold storage has truly realized the inviolability of personal assets and is not subject to the supervision of others
if you want to know more about bitcoin information, please send me a private message and avoid detours
certainly not safe,
can not be compared with bank accounts.
the Unicode encoding of one Chinese character is two bytes, and 16 Chinese characters are 32 bytes, which exactly corresponds to one key
therefore, as long as you remember 16 Chinese characters, you can firmly grasp this wealth
