Yes - that's right. It's written under your deposit address: "Minimum deposit 1 ETH", it's written on popup when you hover over this text: "Please, do not send less than 1 ETH or we will not able to post it to balance and they will be lost!", it's written in our rules here: https://c-cex.com/?id=terms "If you see "Minimum deposit" sign below coin address - it mean that we can't post any deposit of this coin lower than mentioned amount and such your deposit will be lost."
Where else you want us to inform you that you will lost your coin if you send lower than warned minimum deposit amount?
From the technical side we have to limit minimum ETH deposit amount because of our unique technology where we provide personal ETH address to each customer. Of course we have to resend each deposit to our main address in order to make withdrawals possible from it. Each resending cost ETH fee. In case we do not make minimum deposit limitation then it will be possible to send us millions of 0.00000001 ETH deposits and spend all our balance into resending fee. We don't want that so we made restriction on minimum of 1 ETH deposit. Please, note - we do not charge our traders any fee for deposits but we are paying ETH commission for each ETH deposit.
