1. When we dig up bitcoin, we will eventually turn it into money in the bag. First of all, you need to find a bitcoin website that can be traded on the Internet, and then sell bitcoin through the platform of the trading website. Here, we focus on how to sell the bitcoin we g up. Here is a brief introction to the operation method
tools / raw materials
bitcoin
the first step is to transfer out your own bitcoin
1 take my trading platform as an example. The website of the trading platform is: https://vip.btcchina.com/ , click the "register" button to create a trading account of our own
2 after we have completed the registration process and successfully logged into the bitcoin trading website, Click the "bitcoin recharge" link on the left side of the page
3, and then you can see in the right pane that the system will automatically generate a bitcoin recharge address for us, and the status is waiting for recharge. Remember this address. In a moment, we need to transfer our bitcoin to this address in our own mining website
4 next, we open our own bitcoin mining website, namely the mining pool website. I was mining in BTC guide, so I opened it https://btcguild.com/ Website, log in with my own account
5, and then click the "manual payout" button on the page to manually transfer out bitcoin
6 because I don't have enough bitcoin at present, I can't complete this operation, so I can't demonstrate it here. If you have g up bitcoin, you can remit your bitcoin to the previous recharge address of the trading platform through this entry
7 when we successfully recharge to the trading platform, we can go back to the trading platform and click the "transaction query" option under the transaction to see all our transaction records, including the recharged and sold bitcoin. Here we can see that there was a recharge record in June this year
the second step is to sell our bitcoin on the trading platform
1 when we successfully transfer our bitcoin recharge to the trading platform, we can sell our bitcoin on the trading platform. On the trading platform, click the "sell bitcoin" option under the trading column
2, then select the type of order to sell and the quantity of bitcoin to sell, and click the "sell order" button to continue
3. After the order is placed successfully, you can see a prompt message
4. Similarly, the record of selling bitcoin can also be seen in the transaction query under the trading column
5 when the transaction is successful, you can withdraw cash into your own bank card through RMB. Under account management on the left side of the page, click "RMB withdrawal" and fill in the required format in the right pane. Finally, you can click the "withdraw" button
note: the minimum withdrawal amount of this trading website is 200 yuan. In addition, if the mobile phone can't receive the verification code, you can also click "get voice verification", and a phone will automatically call the mobile phone to report the verification code
6 finally, the system prompts that the withdrawal is successful
summary
1 no matter which trading platform you are in, the general process is to transfer the bitcoin you currently dig into the bitcoin address designated by the trading website. When the transfer is successful, you can sell your own bitcoin on the trading platform. Of course, if you want to sell in, you can do it on the trading platform website.

2. Compared with okpay, rchange's perfect money is more abundant, but it is also very nervous. It usually releases reserves around 5 pm every day. Today, I will introce how to recharge btc-e through perfectmoney. The process is similar to recharging btc-e through okpay. The first step is to http://www.perfectmoney.com/?drgn=1 Register an account. This gives you an intermediate perfectmoney account. Second, recharge the perfectmoney account. In http://rchange.net/ Register an account. The website supports recharging from UnionPay card to perfectmoney account. Third, you can recharge btc-e through perfectmoney account after entering the website. Then China UnionPay - & gt; https://rchange.net/ -> http://www.perfectmoney.com/ -> & gt; Btc-e is recharged.

There must be radiation from virtual currency mining, including mobile phones and computers, not to mention mining
Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the networkit can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network
this process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin
however, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks
after the last bitcoin issue, mining is still necessary
extended data:
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of display card, which consumes a lot of power
one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency
At present, there are more than 100 kinds of digital currency in the worldbitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly
nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization, which has very high mining efficiency
resources: Network - bitcoin mining machine
4. 1. First of all, you need to know the concepts of public key and private key (you don't need to read this part already)
public key and private key are terms in asymmetric encryption of modern cryptography. They usually encrypt information with public key and decrypt information with private key. Why? Because when you watch TV dramas, telegrams are encrypted symmetrically. The disadvantages of this encryption method are obvious. If someone knows the key and encryption method, they can decrypt the telegrams according to the encryption method. Until asymmetric encryption, the situation has changed. Public key is the key that can be made public all over the world. For example, when you communicate with Google, you encrypt with the 1024 bit public key given by Google and send it to Google. Only he has the corresponding private key, and only he can decrypt it, so the communication security is ensured
2. Bitcoin mainly uses ECDSA, which is the elliptic curve signature algorithm, This algorithm has two characteristics. Note that these two points are very important to the following
A. as long as you know the private key, you can calculate the corresponding public key
B. If you have signed something with the private key, you can use the public key to calculate whether you signed it or not
3. After knowledge preparation, let's start with the transaction of bitcoin. In fact, bitcoin has no wallet, only transaction bills, and the whole bitcoin is a lot of transaction bills
for example:
bill 1 transfers from a to B to XXX bitcoin
Bill 2 transfers from B to C and D to XXX bitcoin
bill 3 transfers from C to e to XXX bitcoin
.... Anyone who downloads the client can receive all the bills from the day when bitcoin was established, so as long as all the bills are downloaded, they will naturally know how much money should be left on each account (think carefully here)
4. The account of bitcoin is the public key mentioned just now
5, Here is the core part!!! Each bill is a piece of data. After you sign it, it will be sent to the whole network, and the data structure will be reversed into easy to understand Chinese. The explanation is as follows:
from (who sent it, including two parts)
previous TX: the ID of the bill for which you want to spend the money, that is to say, any money you spend should have been transferred to you, You need to show the ID of the bill
scriptsig: your signature for this transaction is to hash the bill with your private key, only you can do this hash
to (who accepts, including two parts)
value: how much to send
scriptpubkey: the public key of the other party, and the bitcoin account is a public key
6, How to send it? Bitcoin communication is not so complicated. You can compare it to IRC channel, but different from ordinary "IRC", any client is an "IRC" server. When you start the client, you will receive the client address with public IP around, that is, the "server" list. This list is constantly refreshed, and it is all other bitcoin users, So when you shout a word in this "IRC", people around you will hear it and spread it all over the world
7. After sending the signature to the whole world, all the clients who receive this list will verify whether your signature is correct, whether you sent it, and whether you have so much money (according to the historical transaction, you can calculate how much money you have to spend)
if you have calculated this transaction, it's OK, Basically, the transfer is successful
8. In fact, the other party has accepted bitcoin, but in order to spend it, he must have the private key corresponding to the address (public key). So he can fill in the from header of a form. Previous TX is the serial number of the transaction just now. Scriptsig fills in the hash signed with his private key...

5. I personally think these virtual coins are not suitable for our ordinary people, because their regulatory authorities are not very clear, and this kind of thing is not very mature. For example, on the surface of P2P, the state has issued a lot of policies to support and supervise, but in fact, when something goes wrong, we can't find the relevant departments to make decisions for the people!
6. Debit card processing conditions:
under 16 years old, accompanied by guardian with ID card and household register
at least 16 years old, you can go there with your ID card
the process of applying for bank card:
bring ID card and a small amount of cash to the bank outlets
fill in the form with the assistance of the staff in the bank lobby
queue up for the number and the ID card with the help of the staff
call at the counter, go to the counter and hand the completed form and ID card to the bank teller. When handling the card, you need to sign and enter the password. The password is six digits. After setting, you should remember it. This is the withdrawal password in the future
you will get a bank card after all processing is completed. If you handle online banking business at the same time, you will get a U shield at the same time
complete the card application and leave with your belongings.

7. Bitcoin's offer has been falling (by the way, it hasn't fallen yet), and some people are wondering - what's the bottom line of bitcoin's offer? Is there a quotation point, once it falls, it will stop by itself? It happens to be interesting to study such a monetary value in the inflation market
generally speaking, the value of money depends on its activity: the central bank prints a lot of money and puts it into the economy with high-speed monetary activity. Therefore, we find that if the value of money decreases, we will be more inclined to sell in the future, resulting in a further decline in the quoted price. This cycle will lead to a runaway effect
for bitcoin, there is no high speed activity of bitcoin. Only the speculative bubble burst, and the quotations get closer to the mall balance point. This leads to a humorous question: where is the balance? First of all, let's make some assumptions. If in the future, no one in the world will hoard bitcoin at all: no one believes that bitcoin will rise, but will only fall in the future. Therefore, in the near future, we will only purchase procts by purchasing just enough bitcoin. In this way, the quotation of bitcoin depends entirely on the demand (the amount of bitcoin that people spend on purchasing procts and services) and the supply (the amount of bitcoin that exists). We are going to test to set up a lower bound: there will be some conjecture data in it, so we are going to choose the more extreme (disappointed) data. Data results are relatively small, and are affected by many factors, but data results can let us roughly know the magnitude of the answer to the question. In addition, we have the same assumption that everyone has lost interest in all counterfeit coins: we only pay attention to the bitcoin quotation supported by the bitcoin demand brought by real procts and services, that is to say, we do not use the statistical data of business channels to count the demand
let's get started. It is an excellent representative of the total demand of bitcoin for procts and services. It is the total activity of coinbase and bitpay, the two largest bitcoin payment processors in the bitcoin instry. Of course, bitcoin for procts and services also occurs in other places (this does not include the bitcoin compensation paid by some companies). The total bitcoin traffic of these two payment processors can exceed 50% of the bitcoin demand in all bitcoin businesses: the service of all large-scale commercial bitcoin transactions is coinbase or bitpay
surprisingly, neither coinbase nor bitpay clearly revealed their detailed business data. Fortunately, we can make a reasonable and accurate guess about the implied meaning of some articles announced by them. For example, we know that bitpay's business volume in 2013 was $100 million, and we also know that its business volume in 2012 was $3 million. Bitpay was founded in 2011, so we can reasonably guess that the total business volume of bitpay at the end of 2013 will be at least $94 million. Coinbase didn't disclose similar data, but both sides made clear the detailed number of cooperative businesses: bitpay is "more than 30000 businesses", coinbase is "31000 businesses". If we assume that the average bitcoin business volume of each of the two payment processors is similar, then the revenue of coinbase and bitpay are very similar. Let's calculate according to this. They are all US $100 million per year, or the remaining 50% of bitcoin needs that do not flow through coinbase and bitpay will bring us $300 million per year. In fact, since it is almost certain that there will be a continuous increase in 2014, these figures are likely to be higher. Since it is difficult to evaluate the detailed increase, let's leave it alone and simply assume that it will be $300 million in 2014
according to the current quotation of bitcoin (US $474), the total value of bitcoin mall is about US $6 billion, so US $300 million only accounts for 5%. That is to say, 95% of the total demand for bitcoin is speculative. Therefore, our estimation of the lower bound of bitcoin price is 23 US dollars. At this moment, the natural market's strength will prevent the price from further falling
let's analyze the above achievements reasonably. Our approximate data comes from bitpay and coinbase's bitcoin traffic (2013), and the bitcoin traffic of the three major business channels is accounted for by the partners working in coindesk. The channel traffic of bitcoin business is mainly speculative business (and counterfeit money business), which can hardly represent the business needs of bitcoin brought by any procts and services. At the same time, the three major business channels in the world (Mt. GOx, bitstamp, btc-e) account for 93% of the total amount of bitcoin shopping malls, and 7% are not included. We think that it is appropriate for the real commercial bitcoin demand to account for 5%
but will bitcoin really fall to $23? Very likely not. Let's assume that bitpay and coinbase did not increase in 2014, which is 100% wrong. Overstock, a US online retailer, Dell, a global PC retailer, and Xindan, a US e-commerce channel, announced in 2014 that they had accepted bitcoin payment, so the real amount could be several times higher. In addition, no one can store bitcoin and counterfeit coins at all. Therefore, this achievement is likely to be far lower than the low bound of the actual quotation, but it also gives us a general idea of where the equilibrium point of the market can exist, and the current bitcoin quotation is actually unsustainable.
