First of all I had to create an account in this exchange since I personally did not use it, it has a very understandable platform with good graphics, I was very surprised by the large amount of cryptocurrencies that you find listed, I see that their fees are based on the volume of btc that are traded in 1 month and are classified in 10 levels
The maker orders are "passive" limited orders published in the order book before the transaction.
Example: If the current market price is 1000 USD and you have created a maker order of 999 USD, the order will not be executed. Instead, it will be published in the order book, allowing others to accept it. Once the order has been executed, the maker will charge the commission maker and the taker will pay the taker commission.
has a large volume of btc trading which is clear to me because it is the largest exchanges.
Postscript: I prefer Binance
