How about setting the minimum fee for transferring to BTC

1.

It's about 37 yuan

let me first introce the reward mechanism of bitcoin system

bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping

there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years

at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin

about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc

2. 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.

3. Bitcoin transfer fee is a fee paid by traders to miners, which is used to encourage miners to compete for bookkeeping and provide enough computing power for bitcoin, so as to ensure the security of bitcoin network. In some places, it is also called miners' fee
when users initiate a transfer in bitcoin network, they usually need to pay a certain transfer fee to the bookkeeper. The transfer service charge is generally 0.001-0.0015 bitcoins. Due to the limited capacity of the block to hold transaction records, miners will give priority to the transaction with high service charge, so the overpaid service charge can be recorded faster
the existence of bitcoin transaction fees can improve the transfer threshold, effectively prevent the blockchain from being full of junk information, and ensure that the miners still have the motivation to maintain the bitcoin network after bitcoin is g up.

4. Most of this is e to the low handling charge you pay. Because bitcoin network will give priority to the transaction with higher service charge. If a transaction is not confirmed for a long time, it may be returned to the issuer. But it's very unlikely. You

5. It's really difficult to mine now. First of all, determine whether your positioning is correct. As mentioned above, you may not be able to play one in eight years in ten years. Of course, you are lucky to dig out a few in one year, but this is gambling. The probability is very small, ha ha

however, you really regard mining as fun and entertainment. If you don't care much about whether you can dig, you can also let your own machine dig all the time. However, the machine configuration above you should not be low, but it is not suitable for mining, just as the swimming champion is not necessarily good at mountain climbing

generally speaking, mining machines mainly focus on graphics cards, which have little to do with processors, main memory boards and hard disks. Of course, they need to be stable and not crash for a long time. In fact, a card is more suitable for mining. In principle, you can go to the network. It is said that before the emergence of R-Series a card, the card with good mining effect was not hd88708750, But we despise the old graphics card that has been eliminated

7. In theory, at the last moment of bolt tightening, the stress on the bolt reaches the allowable strength of the bolt (determined by the strength level of the bolt (e.g. grade 8.8, when the tensile stress of the bolt is 800N / mm2). The force on the bolt can be calculated according to the diameter of the bolt. According to the diameter of the bolt (take the pitch diameter of the thread) and the pitch of the bolt, the inclined angle of the bolt is obtained; According to the static friction coefficient between the pressure (i.e. the force acting on the bolt) and the material, the thrust can be obtained. The thrust multiplied by half of the pitch diameter of the thread should be equal to the torque of tightening the bolt. The moment divided by the arm length from the point of action of the force to the center of the bolt is the force required on the wrench. Of course, this is not the preload of the bolt.

10. In the process of digital currency transfer, such as BTC and eth, miners' fees need to be paid. Miner's fee is the fee given to miners in the blockchain network, which can encourage miners to package transactions and maintain the safe and stable operation of the blockchain network. Miner fees can also be understood as transaction costs in blockchain network, similar to transfer fees in daily life
characteristics of miner's fees:

miner's fees are constantly changing, and the specific amount is determined by the status of the blockchain network at that time
different blockchain networks have different ways to calculate miners' fees
the higher the miner's fee is, the better the transaction will be packed by the miner
not all token transfers need to pay miner's fees, for example, EOS and Tron transfers do not need to pay extra miner's fees
