Bitcoin does not cash
users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items. In the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. During operation, bitcoin users enter a password similar to the bank pin code to log in to the network bitcoin account
through the ATM, users can withdraw the Canadian dollar cash corresponding to the ratio from the bitcoin account, or deposit the cash into the bitcoin account
bitcoin users only need a smart phone to use bitcoin, which is similar to online shopping. A bitcoin address is about 33 characters long, a string of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"
bitcoin address and private key appear in pairs, and their relationship is like bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet.
Take bitcoin to the OTC platform and sell it in RMB
Bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, the open source software and the P2P network on it were designed and released. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals

As long as the influence of bitcoin scam is not particularly bad, the government generally adopts the policy that the people do not sue, the officials do not blame, and turn a blind eye to it. Because even if the government enters, it is difficult to find the culprit. The information of some operation teams is not public, and it is difficult to find it on the Internet. Some of them are still abroad, so it is difficult to solve the case. Some of the culprits turn around and become victims. There are also those who participated in the bitcoin pyramid scheme. A large number of victims are also the biggest accomplices< br />
the new BSC is basically optical port BSC. Go directly to SDH or PTN equipment on the transmission side, go to the base station side through the transmission network, and convert it into 2m electrical signal to the base station (BTS). Some base station equipment support the optical port, and may be directly inserted into the optical fiber.
first of all, register an account in one of the five major domestic platforms for real name authentication, and bind the bank card and mobile phone number
secondly, recharge the bitcoin to the trading platform, and then sell it.
finally, withdraw the RMB balance of your account into your bound bank card.
because bitcoin is just a psychological currency at present, it is not allowed to withdraw cash from any channel
for those small partners who invest in bitcoin, if they need to withdraw cash in the process of investing in bitcoin, they need to do it through offline transactions rather than through the so-called financial management software. At present, many countries and regions do not recognize bitcoin as a virtual currency, and even some regions have listed bitcoin as a strictly prohibited object of speculation
bitcoin's sudden plunge
after landing $65000 before bitcoin, the current bitcoin is in the callback stage, and there will be a periodic plunge almost every once in a while. Now bitcoin has a big drop compared with before, and it is about $50000 at present. Because bitcoin's market is not stable, sometimes it can plummet by thousands of dollars in just one hour, which also leads to many people's positions bursting and losing money{ RRRRR}
some people say that one day in the coin circle, ten years in the world , which is not too much. I think investing in virtual currency is not suitable for most people, just like riding a roller coaster
sometimes, we need to perform some operations in the container on the host computer. Of course, this operation mode of bypassing docker is not recommended
if you are using a relatively new docker version, you will be embarrassed to find that if you use the system command directly, you will not be able to access the container namespace
here, we first introce the "IP netns" series of commands. These commands are responsible for the network namespace in the operating system
first, we use the "add" command to create a temporary network namespace
IP netns add test
then, use the show command to view the network namespace in the system, and you will see the newly created test namespace
IP netns show test
in addition, a very useful command is exec, which will execute the command in the corresponding namespace. For example,
IP netns exec test ifconfig
use the Del command to delete the newly created test namespace
IP netns del test
next, run a docker container, such as
docker run - it Ubuntu
execute the IP netns show command again. Unfortunately, there is no output here
the reason is that docker will still create a new namespace with the process number after starting the container, but in the newer version, the namespace information file in the system is deleted by default
the network namespace file is located under / var / run / netns. For example, the test namespace we created earlier has a test file in this directory. System commands such as netns rely on these files to get information about the namespace
after the container is started, you can see that there is nothing in this directory
OK, let's rebuild it manually
first, use the following command to view the container process information, such as 1234 here< br />docker inspect --format='{{. State.Pid}} ' container_ ID 1234
next, under the / proc directory (which stores all the relevant information of the process), link the corresponding network namespace file to / var / run / netns
ln - S / proc / 1234 / NS / net / var / run / netns /
then, you can view or access the container's namespace through normal system commands. For example,
IP netns show 1234 IP netns exec 1234 ifconfig eth0 172.16.0.10/16
