After BTC hit 11700

1.

2. 1. The smallest bitcoin unit is 1 Cong, or 0.00000001btc
2. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
3. Unlike most currencies, bitcoin does not rely on specific currency institutions. 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 currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. 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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.

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. BTC should be BTC (BOT Tennis Club)

the dream fund is an entrepreneurial business selection. In the process of holding, there is BTC, which is to let the contestants manage a manageable tennis club, and finally see who wins the most profitable

refer to:
1. Business plan audition - Top 50

2. The selection of prospective entrepreneurs: 50 in 30

this stage is divided into three parts: business plan evaluation, on-site propaganda and on-site defense. The shortlisted 50 teams will be divided into three groups, each of which will give lectures on campus according to their own business plans in three universities, and receive questions from the jury at the same time. The organizing committee will publish the shortlist of 50 teams on the official website of "Dream Fund", as well as the grouping situation of the shortlist, the time and place of campus publicity, and the time of submitting the demonstration text of the business plan. In the second round, 30 indivial teams will be selected to enter the final election of "Dream Fund" and "BTC (BOT Tennis Club) top 10 entrepreneurial stars"

3. "BTC star of entrepreneurship" general election - 30 into 10

"BTC star of entrepreneurship" selection is divided into three parts: business plan propaganda, on-site defense, talent show. BTC star will finally select 10 team indivials. At the same time, the "online public version" business plan with the highest network support rate as of the day of the runoff was announced. The indivial team was selected as the "Internet popularity star"<

4. BTC Star Award Ceremony

all the top 30 team indivials will be invited to participate in the "Dream Fund" award ceremony: the top 30 team indivials (excluding the top 10 venture stars) must send one representative to participate in the "Dream Fund" award ceremony, and all the top 10 venture stars will participate in the award ceremony. BTC star will be honored, awarded and signed at the ceremony

at the ceremony, the "lunky star" was selected as the winner of the live camera lottery. The ceremony will present prizes to the 30 shortlisted indivials

5. BTC Star Training

in December, the Organizing Committee of "Dream Fund" will set up an expert group to conct special, targeted and targeted training for BTC star in terms of tennis club operation. During the training period, BTC star will be assessed regularly, and the qualified team will start "Dream Fund" to operate the club with 50000 yuan< BTC venture star will officially launch BTC tennis club on January 1, 2011. After the start of the club, the Organizing Committee of "Dream Fund" will have an expert group to provide advice and help for the club. The club must submit the income and expenditure report and operation analysis to BOT every month. Bot will supervise the operation of the club from time to time

the management right of the tennis club operated by the winning team / indivial using the 50000 fund belongs to the winning team or indivial, and the ownership belongs to the sponsor.

5. 1. According to the bitcoin mining mechanism, it will eventually be infinitely close to 21 million, but it will never be reached
it can be roughly understood as the relationship between 0.9 (9 infinite cycle) and 1
2. Even if there is only one bitcoin left in the world, it means that there are 1000 0.1 bitcoins and 100000 0.01 bitcoins in the world
let's assume that the function of bitcoin is equivalent to that of gold as a currency anchor (in fact, it also has this function). You will understand that there are 21 million bitcoins in the world and only 0.1 bitcoins in the world are the same. The currency itself or bitcoin

for example, if the number of bitcoin in the world is reced to one tenth, the market price of bitcoin should be 400000 yuan (to understand this needs a certain economic basis)

so whether bitcoin is in circulation or not has nothing to do with the quantity.

6. In the last rising cycle, BTC usually experienced multiple 30% + correction, and the average increase after each correction was 153%. That is to say, if you can buy accurately at every low point, you can get an average return of 150%
since then, the pie has risen to US $14000 for more than a month. Today, it has been nearly two months since this high point. At present, the range of shock is almost a 30% callback
so, according to the historical situation, we are likely to experience another 150% rise this year? And if it can be realized in the next few months, it also means that the bear market is really far away from us:
however, it should be noted that the above is based on the rising cycle in history, and now, logically speaking, we can't be 100% sure that we must be in a rising cycle now. If we choose this chart today, we also want to remind the players who are looking at the general trend, Or we should be cautious to do some catch-up and sell down, or wait for a "bottom hunting" point, because it is possible to miss one or two times the income of ten or twenty points
time really flies. It is expected that bitcoin will rise to US $15000 by the end of the year

7. Through these ports 135.137.138.445
preventive measures:
1. Start the firewall of windows first
2. Right click the network icon in the lower right corner - Sharing Center - Windows Firewall - Advanced Settings - inbound rules on the left - new port on the right - TCP - input these ports - deny access

8. No, bitcoin was born at the end of 2008, and blockchain technology was well known 14 or 15 years later. It is the large-scale application of bitcoin that makes people pay attention to the underlying technology of blockchain.

9. Domestic recommend okex, technology is the most reliable, using distributed server cluster and distributed storage technology, in short, do not go to a small exchange.

10. In the long run, bitcoin will definitely rise. I think I can buy it at any time now, but the exchange should choose carefully. The domestic reliable one is okex, which is relatively safe. Bitcoin can be bought very fast, and it can arrive in the account in one minute. If you have any questions, please feel free to ask
