Inside: Why do I need a commission on the Bitcoin network, can I not pay it?

With the traditional money turnover, we pay a commission to banks, payment services, exchangers for the fact that our transaction is completed.

If it is easier to look at, then the commission for any service in a conventional payment system consists of the Profit Service and Funds for maintaining the work of the resource.

But why is there a commission on the Bitcoin network? there are no central nodes?

The Bitcoin network does not imply the existence of any central control nodes, and when making a transaction, you send it to the free float of the Bitcoin network.
There, it is added to a wad of generated money and remembered forever in the system.

But as you understand such transactions, the sea, and in it your money transfer can drown, no, of course, after some time it will be confirmed by the system, but what if the money needs to be transferred as soon as possible?
- Pay a commission
It will not go to the bank, but precisely to the people who added your transaction to the found block of coins.

Commission calculation

Please note that miners (miners of coins) can set a certain commission for their services, and if there are many such miners, then for an early transfer it is better not to regret the commission to the transaction.

But the Bitcoin system is able to self-regulate, it is impossible to agree with everyone and raise the commission by 146%, anyway there will be someone who has a minimum commission when processing will be 0.00001 BTC.

The fee depends on the size of the transaction, for every 1000 bytes you have to pay 1 share of the fee, it is equal to 0.0005 BTC

In addition, if the transfer amount is less than 0.01 BTC, then it is again subject to a commission.
But pay attention! No one forces you to pay a commission, if you don’t pay it, the transfer will come true, but after a while.

When the payment is not subject to commission

- Transfer over 0.01 BTC
- Translation does not take up much space in the block
- Bitcoins with which the transaction will be performed have many confirmations
