1. 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.

2. 1. By the time of delivery, the system will take the arithmetic mean value of BTC (LTC and other currencies) dollar index in the latest hour as the delivery price to close out all open contracts in the current week. The profit and loss after closing the position shall be added to the realized profit and loss
2. If there is still a user's strong order that can not be completed until the delivery, the position will be delivered according to the delivery price at the time of delivery, and the resulting loss will be recorded as the loss of the through position user of the contract. After the delivery of the contract in the current week and the settlement of the contract in the next week and quarter, it will be apportioned according to the full account apportionment system to make up for the losses of the customers who cross the position
3. Add the realized profit and loss of the weekly contract into the account balance, and the settlement is completed< br />4､ If there is market manipulation or market abnormality around the time of delivery and settlement, which leads to significant fluctuation of the index or abnormal allocation proportion, we may choose to postpone delivery and settlement according to the specific situation, and the specific rules will be announced
delivery time: 16:00 every Friday (UTC + 8)

3. You can only buy the genuine one

4. Absolutely. I've experienced it myself. After joining the dish is the man, soon cut leeks.

5. I'm not sure if there are any mining machine manufacturers in Xiamen, but there are bitcoin mining machines in Shenzhen nearby. If you want to buy Mining machinery, you don't need to buy it in Xiamen. Don't you just buy it online? At present, the bitcoin instry is in recession, and the price of bitcoin continues to decline, but the computing power of the whole network is still growing slowly. The cost recovery of some first-generation and second-generation ASIC mining machines is basically far away. Unless the price rises, don't be fooled by some mining machine manufacturers. If you want to join the mining army, it is suggested that you buy Avalon third-generation mining machines.

On June 29, 2002, at the invitation of UNESCO, 45 young people from Russia are going to fly to Spain to enjoy a two-week trip in Barcelona. Among them, there are painting prodigy, gymnastics champion, all of them are the most intelligent and talented children, which can be called "elite youth league". Unexpectedly, the leader made a mistake and missed the flight at the airport, so he had to change the ticket after 2 days

on the evening of July 1, an airliner took off smoothly and took the children on the journey to Barcelona. At the same time, a Boeing 757 freighter full of cargo took off for Brussels at Bergamo International Airport thousands of miles away. The routes of the two planes intersect over southern Germany

at the air traffic control center in Zurich, Switzerland, Peter Nielsen and another air traffic controller were on ty that night. They were responsible for dispatching planes over the German Swiss border. Because there are few planes at night, Nelson's colleagues even skip work and go for a walk. The radar screen several meters away is left to Nelson

at 11:10 p.m., the technicians came to the air traffic control center to repair the radar. This work will not only shut down the communication system, but also slow down the radar scanning speed once the maintenance work starts. When the aircraft is too close, no warning image will be generated. This action has laid a fuse for the tragedy behind

at this time, the Russian airliner is heading for Switzerland. After leaving German airspace and entering Switzerland, German ATC handed over the command of the aircraft to Nielsen

another Boeing 757 freighter has just overflew the alpis and is ready to enter Swiss airspace. Captain Phelps asked for the climb height, so the thin air would rece the resistance and save fuel

The air traffic control center approved the request, and the Boeing 757 cargo plane quickly climbed to 10800 meters. However, the Tu-154 was also at the same altitude and was on the collision course. But at that time, the distance was still far away, and there was no danger for the time being

in the air traffic control center, Nelson, a man on ty, is busy, but he is constantly receiving new scheling tasks, so he has to move back and forth in front of two radar screens to ensure the smooth progress of the scheling task. But he did not find that the Tu-154 and Boeing 757 were flying towards each other at the speed of 1000 km / h

in general, as long as the aircraft is too close, the radar will give an alarm in advance, but this time, the equipment failed and did not work normally. The German air traffic control center found something abnormal, but according to international regulations, they could not directly communicate with the pilot, so they had to immediately inform Nelson to dispatch him. Unfortunately, Nelson couldn't get through

At the moment when the two planes were about to collide, Nelson finally found something wrong and immediately instructed Tu-154 to descend. But at this time, the aircraft's anti-collision system issued a warning, let the aircraft climb height. In the face of these two commands, Captain Alexander thought that the human command was more reliable. He did not follow the advice of the anti-collision system, so he cancelled the automatic driving and lowered the putter height

the tail of the Boeing 757 is like a sharp blade, which cuts the Tu-154 into two parts, and the plane explodes and disintegrates instantly. Boeing 757 lost its tail, and after two minutes in the air, it also crashed in ublingen, a small town on the German Swiss border

after the plane crash, Germany sent out more than 6000 rescue teams to look for the survivors. However, after six days of search and rescue, they only found bodies and debris all over the mountains, and all 71 people on the two planes were killed

extended information

accident investigation:

on the night of the incident, only Pete Nelson, an air traffic controller in Zurich air control center, was in charge of the flights in this airspace. Other air traffic controllers rest in another room, which is not in line with the regulations, but the habitual behavior of air traffic controllers has been acquiesced and ignored by the relevant management agencies for several years

because the air traffic control station was in the overhaul period, several other air traffic controllers and department heads were ready to change shifts at any time that night, and Nelson didn't realize this, or he didn't want to let his colleagues take the risk of fatigue work

In addition, a ground-based optical collision warning system used to alert air traffic controllers to avoid collision was shut down e to routine maintenance before the accident, which Nielsen did not pay attention to

another audio anti-collision warning system installed in the air traffic control center issued an audible alarm 32 seconds before the collision at 21:35 p.m., but it was not heard by anyone. The technical inspection of the equipment also confirmed that it was in good working condition. The Skyguide special line telephone of the air traffic control center was temporarily cut off e to the maintenance work. This telephone could have received the alarm from the air traffic controllers of Karlsruhe air traffic control station in Germany on the abnormal situation of the airspace

a minute before the crash, Nelson directed a late Lloyd's flight to Friedrichshafen airport. He used a faulty telephone system and was so busy between the two control stations that he didn't inform the Russian pilots to lower the altitude until about a minute before the crash

if he can give an alarm earlier and separate the routes of the two aircraft in time, the anti-collision system of the two aircraft will not be activated. When he felt that he could not cope with the work of two control stations at the same time, it was too late to call other air traffic controllers for help
