How much does virtual currency exchange charge for buying curren

2. I'm not sure about the current handling charge. However, it is said that ring the event from 00:00 on February 17, 2018 to 23:59 on February 19, 2018, all new and old users will be free of charge for full currency recharge and withdrawal, and there is no limit on the number of transactions.

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. The okex bitcoin exchange will charge different transaction fees according to different levels. The standard of handling charge for currency transaction and currency leverage transaction is the same. If you are not clear, please ask at any time

5. For example, easybtc, ordinary users do not need any fees to buy or sell. That is, some advertisers need to spend money, you might as well register to experience it.

6. It depends on which platform you trade
some platforms are free of charge, while others need to be charged. Even if they are charged, they are all within 0.3% or about 0.1%.

7. Anyway, TOBI is not high. Relatively speaking, it's OK. Some of the lower ones are not recommended. They are not reliable.

8. Bitcoin transaction refers to the transfer between an address and another address, which usually requires an additional service charge to miners

generally, an ordinary bitcoin transaction is composed of one input and two outputs, with the size of about 200 bytes. The default charge is 0.0001btc for every 1000 bytes, and the ordinary bitcoin transfer fee is about 0.001-0.002btc

however, e to the limited capacity of the block to hold transaction records, miners generally give priority to the transaction with higher handling charges. Therefore, when the transaction needs urgent confirmation, it is recommended to select custom charges. I also saw these in Yingfu College of Finance and economics.
