Small bitcoin

2.

Strictly speaking, there is no issue price for bitcoin. In 2010, a programmer bought a pizza with 10000 bitcoins, the first bitcoin deal

bitcoin does not rely on a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. 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 feature and algorithm of P2P can ensure that it is impossible to artificially control the value of bitcoin by mass manufacturing. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

extended data

principle

starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote

and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client

after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

network bitcoin

3. It is often said that you can send bitcoin to any corner of the earth for free. Generally, you can transfer bitcoin for free, but in some cases, you have to pay transaction fees to complete the transfer. In version 0.8.3 bitcoin wallet, the default is 0.0001 bitcoin transfer fees. This service charge is awarded to miners to encourage them to continue mining and provide enough computing power for bitcoin to ensure the security of bitcoin network. At present, the main income of miners is to get 25btc reward by creating new blocks, but this reward is halved every four years. As time goes on, bitcoin transaction fee reward will graally replace the reward for creating new blocks. Under what circumstances do you need to pay the handling charge? How much does bitcoin charge? What is the handling charge? Bitcoin system has a series of network rules, including fee rules, which are "what the client should do". When you use bitcoin client (wallet, bitcoin QT) to send bitcoin, the whole process is roughly divided into the following steps:
1. Prepare the bitcoin you want to send. The client is responsible for collecting the balance of bitcoin in your wallet (bitcoin QT) to prepare for payment, because every bitcoin you receive is stored in your wallet until you spend it. If you receive two payments from 3btc and 2btc, their records in the wallet are independent of each other, that is, a 3btc and a 2btc, rather than merging them into 5btc (the wallet only records transaction details and does not merge the balance, but you can see the total balance on the interface of the wallet). As time goes on, many bitcoins of different amounts will accumulate in your wallet, So when you send bitcoin, the wallet has to decide which bitcoin is the most suitable for this sending. The bitcoin you get in a transaction is called "inputs" and the bitcoin you spend is called "outputs". There are multiple inputs and outputs in your wallet
2. If your outputs are less than 0.01btc (including the fund changes inside your wallet), you have to pay a handling charge of 0.0001, even if you transfer it to yourself. The wallet has an established rule when preparing your payment amount, that is, when preparing the payment amount in many inputs, try to avoid the amount change less than 0.01btc (for example, if you want to pay 5.005btc, the wallet should choose 3 + 2.005 or 1 + 1 + 3.005 instead of 5 + 0.005)
3. The larger the amount, the higher the age, and the higher the priority. If the amount you send is too small or your bitcoin has just been mined, then your transfer is no longer free. Each transaction will be assigned a priority, which is determined by the degree of currency, the number of bytes and the number of transactions. Specifically, for each input, the client will first multiply the number of bitcoins by the time they exist in the block (currency age, age), and then divide all the procts by the size of the transaction (in bytes). The calculation formula is: priority = sum (input)_ value_ in_ base_ units * input_ age)/size_ in_ If the calculation result is less than 0.576, then the transaction must pay the handling fee. If you do have a large amount of small input and want to transfer it out for free, you can add a large amount of bitcoin with a large age, which will increase the average priority, so that you can transfer out bitcoin for free
4. Charge per kilobyte. At the end of the transfer, the client will detect the size of the transfer (in bytes). The size generally depends on the amount of input and output. The calculation formula is as follows: 148 * input amount + 34 * output amount + 10. If the size of the transfer exceeds 10000 bytes, but the priority meets the free standard, you can still enjoy the free transfer, Otherwise, there will be a handling charge. The cost of 1000 bytes is 0.0001btc by default, but you can also add it in the client. Open the tab "settings & gt; Options & gt; The main purpose is to adjust the handling charge. If the service charge you are setting is less than 0.0001, BTC is calculated as 0.0001.

4. The most important concern of small transaction is the rate. In keying cola, it is free to buy and sell all kinds of coins, and only some rates are charged to successful advertisers.

5. Ouyi okex supports a minimum purchase of 10 yuan. No matter how small it is, it's meaningless to invest. Now I make a fixed investment every month. The income is very considerable, and the rate of payment is relatively fast. Generally, it can be paid in one minute.

6. You can choose the trading limit. This is set by yourself and the other party

7. This is supported. How small is the limit set by the advertiser? The minimum limit is 50. You can trade through the advertiser. However, there is a minimum standard for their transfer in and transfer out, which is 0.01btc. So it depends on how you want to trade. This is usually prompted
