Coinmex exchange caught the attention of most traders due to its low flatfee of 0.05% ,this is 5times lower than the industry's average but not the lowest because I have once come across an exchange with a trade of 0.01% , but what still makes Coinmex different from other exchange that charge such a low fee is that their withdrawal fee is also very low and its 0.0004BTC to be precised unlike some other exchange with low maker and taker fee and high withdrawal fee.
It is very sad to know that Coinmex exchange has been shut down and so their URL address has been deleted from the web, the exchange didn't operate for a long time and so just few information about their services are available.
