All Bitcoin exchanges have transaction fees, which will be charged upon completion of each buy and sale order, and the fee rate charged depends on the Bitcoin transaction volume of the exchange. In addition, different transaction fees will be charged according to the way you move the funds when you deposit and withdraw funds on the exchange. In general, comparing with credit cards, PayPal, etc, the fee of bank wire transfer or direct remittance is lower because it is less risky to the exchange. However, credit cards are very convenient ways to deposit funds, so most people use it.

In addition to transaction fees and transfer fees for funds deposits and withdraws, traders may also need to pay "currency exchange fees.” For instance, if you pay KRW to an exchange that only trades in U.S. dollars, the bank or exchange may charge a currency exchange fee to exchange KRW into U.S. dollars.

Maker and Taker

The role of the trader in the transaction will be divided into "Maker" and "Taker" when the transaction is completed. Makers incur smaller fees than takers.

Why is there such a maker taker system with different charges? The main reason is that Makers provide higher liquidity to an exchange and create a market for a token: Takers remove liquidity by fulfilling open orders on the exchange.

Exchanges often calculate the market value of an asset with an order book. This is where it collects all the offers to buy and to sell from its users.Limit orders is that you announce your intentions ahead of time by adding them to the order book. You’re a maker because you’ve “made” the market. Therefore, makers are given some kind of rebate, as they’re adding liquidity to the exchange.  

On the other hand, the takers mostly use "market orders" to place orders on the exchange. Once the exchange receives this type of order, it will take volume off the order book.

Trading fee of Binance 

Binance Exchange is currently the largest exchange in the world. It also provides various  cryptocurrencies for trading. Therefore, each service will have different rates (such as currency trading, leverage, USDT contracts, futures, deposit and withdrawal).

Binance provides that currency-to-currency transactions with a maximum of 0.1% and a minimum of 0.02% handing fee.

The difference in handling fees between these will be divided into 10 VIP levels from 0-9 according to the trading volume of the trading account. Higher level will pay lower transaction fee. In addition to the level, handing fee will also be different by the role you play in the transaction, “Maker and Taker.”

Before trading on the exchange, you also need to register on the exchange and go through a series of verification processes. Once the identity verification is successful, you can purchase cryptocurrencies such as Bitcoin as long as the funds are transferred to the account first. Different exchanges provide different ways to deposit funds. Bank wire transfers, bank transfers, credit card transactions, etc are the common ways. On the other hand, if you want to withdraw money from an exchange account, you can use bank transfer, wire transfer, credit card transfer, Paypal, mail check, or direct cash delivery.

The characteristics of cryptocurrency is that its transaction costs are extremely low. Most the fee of exchanges are similar, and it’s highly competitive between exchanges. Therefore, we recommend you focus on safety of an exchange and user experience .
