1. In August 2013,
experienced the period of bitcoin's soaring, at that time, we were basically staring at the computer every day

2. 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
anyone can run software on specialized hardware and become a bitcoin miner. mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions. Bitcoin miners can earn transaction fees paid by users to speed up transaction processing and additional bitcoin issued according to fixed formula
new transactions need to be included in a block with mathematical workload proof before they can be confirmed. This kind of proof is hard to generate because it can only be generated by trying billions of calculations per second. Miners need to run these calculations before their blocks are accepted and rewarded. As more people start mining, the difficulty of finding effective blocks will be automatically increased by the network to ensure that the average time to find a block remains at 10 minutes. Therefore, the competition for mining is very fierce, and no indivial miner can control the content contained in the block chain
workload proof is also designed to rely on previous blocks, which forces the time sequence of block chain. This design makes it extremely difficult to cancel previous transactions, because the workload proof of all subsequent blocks needs to be recalculated. When two blocks are found at the same time, the miner will process the first block received, and once the next block is found, it will be transferred to the longest block chain. This ensures that the mining process maintains a global consistency based on processing capacity
bitcoin miners can neither increase their rewards by cheating, nor deal with the fraulent transactions that destroy the bitcoin network, because all bitcoin nodes will reject the blocks containing invalid data that violate the bitcoin protocol rules. Therefore, even if not all bitcoin miners can be trusted, the bitcoin network is still secure
sha256 is an encryption algorithm.

3. The transaction cost of bitcoin is generally between 0.0001-0.0005btc. Of course, the amount accepted by each miner and miner's Association is different. Sometimes, a large amount of bitcoin transaction does not need a service charge, such as more than 100btc. Small transactions below 0.01btc will be charged a certain amount of fees. Of course, some bitcoin clients can set bitcoin transaction fee. If you set the transaction fee very low, the transaction confirmation time will be very long
first of all, we should understand that this service charge is given to miners to encourage them to continue mining and provide enough computing power for bitcoin, so as to ensure the security of bitcoin network. At present, the main income of miners is to get BTC reward by creating new blocks, but the reward is halved every four years. As time goes on, bitcoin transaction fee will graally replace bitcoin reward
under what circumstances should the handling charge be paid? What's the amount
bitcoin system has a series of network rules, including the handling charge 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 in your wallet until you spend it
if you withdraw 3btc and 2btc twice in okcoin bitcoin, their records in your wallet are independent, that is, a 3btc and a 2btc, instead of merging them into 5btc (the wallet only records transaction details, but does not merge the balance, but you can see the total balance on the interface of the wallet), As time goes on, you will accumulate a lot of bitcoin in your wallet. It is conceivable that there should be thousands of such records in okcoin bitcoin wallet. So when you send bitcoin, the wallet must decide which of the above records are 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. Prevent a large number of micro payments from impacting the network
if you recharge the okcoin bitcoin trading platform less than 0.01btc (including the fund changes inside your wallet), you must pay a handling charge of 0.0001. When preparing your payment amount, the wallet has an established rule, 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 recharge 5.005btc to okcoin bitcoin, 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 of the currency, 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. This is why you need to add a 0.0001 when you withdraw with okcoin bitcoin, because the bitcoin transfer in okcoin wallet is frequent, and the time of bitcoin in the block is relatively short, so you need to pay a handling charge. If you do have a large number of small inputs, such as small miners, and want to transfer them out for free, you can add a large amount of bitcoin with a large currency age, and the average priority will be increased, so that bitcoin can be transferred out for free
4. Charge per kilobyte
at the end of the transfer, the client calculates the size of the transfer (in bytes), which 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 you need to pay the handling charge. The cost per 1000 bytes is 0.0001btc by default, but you can also add it in the client by opening 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. When this rule applies, it will replace the rule in step 2 instead of accumulating.

4.
Bitcoin network generates a new block every ten minutes. Every time a miner completes a block, he can get a certain amount of bitcoin as a block reward, and the reward will be halved for every 210000 blocks mined. Because the time for mining each block is limited to 10 minutes, at this rate, the period for the reward to be halved is four years, that is to say, the reward for bitcoin blocks is halved every four years
when the bitcoin block reward was halved for the first time, its price rose 25 times from 300 yuan to 7995 yuan; In the second half, the price rose 28 times from 5011 yuan to 140000 yuan. So many people predict that the third halving of bitcoin in May 2020 will lead to a sharp rise in the price of bitcoin, at least 10 times. However, these figures are not so clear. After halving in 2012, bitcoin prices rose for two months, and in 2016, there was almost no immediate response to deflation for a month. This may also be the result of the strategy of "buying rumors and selling news" implemented by some speculators
extended data:
after bitcoin halved, the supply slowed down, and keeping deflation through algorithm has always been a part of bitcoin protocol design. It was set up to ensure the value of bitcoin. By recing block incentives and setting the maximum possible supply of bitcoin at 21 million bitcoins, bitcoin has an anti inflation feature, which runs counter to the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation, and less than 3.5 million bitcoins are available for mining. When the next block award halves, bitcoin's annual inflation rate will drop from the current 3.8% to about 1.8%
maintaining deflation through algorithms has always been a part of the design of bitcoin protocol. It was created to guarantee the value of bitcoin. By recing block incentives and keeping the total amount of bitcoin at 21 million bitcoins, bitcoin is endowed with an anti inflation nature, which is different from the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation and less than 3.5 million available for mining. The next block award cut in half could rece bitcoin's annual inflation rate from the current 3.8% to about 1.8%. This will be the first time in bitcoin's history that it has fallen below the historical average of about 2% - 3% growth in gold supply
5. It's four peaks:
the first time, in March last year, bitcoin soared from tens of dollars to 266 dollars overnight
for the second time, the United States held a bitcoin hearing on September 18 last year. Before the hearing, the Federal Reserve and other relevant people looked at bitcoin. Under the influence of the good news again, the price of bitcoin rose to 8000 yuan
the third time is ring this year's World Cup. Due to the influence of the world cup, the price of bitcoin once approached 6000
for the fourth time, bitcoin suddenly rose to 3000 yuan after six months of continuous downturn and hovering around 2400 for a long time. It is said that it is the entry of hot money.

6. You can trade countless times a day, as long as you have money. But I haven't tried it. I can operate it three times a day at most, but it should also depend on the platform. Some platforms may have regulations that they can't operate many times a day, so it still depends on what platform you choose.
7. Bitcoin (English: bitcoin, abbreviated: BTC, currency symbol: &3647;) It is a kind of user autonomous [source request] and universal encrypted electronic currency [5] [6] [7]
the concept was proposed by Satoshi Nakamoto in 2008 [4] [9] [10]. Then, based on the concept of openness, peer-to-peer, consensus and active participation, combined with the working mode of open source software and block cipher in cryptography, he developed an operating system for bitcoin issuance, trading and account management on the platform of P2P peer-to-peer network and distributed database. The system enables all nodes throughout the peer-to-peer network to reach a network agreement according to their seed files, so as to ensure fairness, security and reliability in currency issuance, management and circulation. And promised that bitcoin will become "e-cash" similar to e-mail. It can avoid inflation without examination and approval, and everyone has the right to issue it; After the payment is completed, the user loses the ownership of the bitcoin. On January 3, 2009, 50 bitcoins came out
unlike traditional currencies, bitcoin's operation mechanism does not rely on the support or credit guarantee of the central bank, the government and enterprises, but on the network agreement reached by seed files in the peer-to-peer network. The decentralized and self-improvement monetary system theoretically ensures that no one, institution or government can control the total amount of bitcoin or create inflation. Its total amount of money graally increased at the designed rate, and the increase rate graally slowed down, and finally reached the limit of 21 million in 2140[ 11]
there are many ways to use bitcoin, which can be converted into local cash or gold coins through electronic currency exchanges, service providers and indivials; It can also be used directly to purchase goods and services[ 12] [13] [14] with the rapid growth of indivials, organizations, businesses and enterprises receiving bitcoin payment, its exchange rate has risen thousands of times in four years[ 15] [16] [17] [18] as of March 30, 2013, the total value of all issued bitcoin has exceeded 1 billion US dollars after being converted into US dollars according to the market price[ 19] [20] [21] although bitcoin is currently the most widely used electronic currency, [1] except that some countries have explicit provisions on virtual currency, no country has made legal norms and guarantees for the issuance of bitcoin.
