Heads up for people.
One of our community lost some BTC on C-cex due to his own error last week.
The error is easily fixable. The BTC remains in C-Cex control and in an address that is linked to the community member's account. Indeed, c-cex have helped other community members with similar problems before. It is a two minute job to resolve.
Three different support tickets have resulted in three totally different answers that contradict each other.
At best, their customer service is in a bit of a mess. At worst, there is something concerning going on.
I'll will post here to update if we see a resolution.
Exercise caution.
A follow up with this issue The BTC has not been returnedWe raised 3 support tickets which have received three different responses. Paraphrased responses as follows: Ticket 1: Sure, we'll recover your BTC and will do so as soon as the wallet is out of maintenance (the wallet wasn't in maintenance at the time). Ticket 2: It is physically impossible to recover your BTC. Ticket 3: We could recover your BTC but it would cost us $500 to do it so we won't. We have issues with this for the following reasons: 1) It is literally a 5 minute job to recover the BTC. 2) It is DEFINITELY possible. We have even told them how they did it before. 3) C-CEX have performed identical recoveries several times in the last few months. 4) If it costs them $500 to type dumpprivkey into a console then they have serious problems. Clearly this is unacceptable and we are now advising members of our respective communities to avoid using C-Cex if at all possible. One final follow up on this issue from me. C-Cex are no longer responding to support tickets about the BTC that they will not return to one of our community members. They might as well be an exit scam for all I care. If an exchange won't return funds to the legitimate owner then they simply cannot be trusted.

Scam fking suckersI make two deposits ETH 0.99 and another 0.2.
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.

c-cex I ask you again to inform me about your inner-team speakings about the serverless altcoin wallet solution so that you can send out delisted coins to customers even after the wallet was removed from the server.
Sorry, we already gave answer. We consider our delisting policy fair. We are not going to develop any serverless solution as it does not look viable to us. Viable. It should not have to be viable for C-Cex. When you hold user funds then these funds aren't yours. When you sold them on another exchange then those earnings are not yours. Expropriate users out of their coins because you do not want to offer trading of that coin anymore does not mean that these coins does not belong to their owners anymore. I ask you again to find a solution. Looks like you are missing one important thing: we make announce at least 2 weeks before delisting in our newsletter that come to Your e-mail, twitter, chat and on main trading page ("Important news") and highlighting coins with red color to let customers withdraw coins we are going to delist. Then we remove markets and give a lot more days for withdrawals (currently we still don't remove wallet delisted from april, 4 keeping them opened for withdrawals). I do not miss that point. The thing is that you have to care for the user funds. They are not funds of c-cex, they are funds owned by the users of c-cex. And if users are not able to claim their coins in the timeframe you offer then it doesn't change the legal fact that you owe these coins. For most shitcoins that is no problem since they are worth nothing but some coins are worth something and you probably hold a lot of those coins. Worth a lot still. So you think it's enough to say we don't want to offer it anymore because that coin is not viable anymore to us, if you for some reason are not able to get your coins back in a certain timeframe we decide on then we will seize your coins. No reimbursement, no compensation. I also give at least a month for refunds for ICO's, which already is double the time c-cex gives, but I still refund after that time. If I wouldn't then I probably would be dark red already. Well, the coins are not mine even though a lot of investors come to me months after the refund started. Well, what is your explaination why you will not refund? It's not viable? Doesn't matter, you decided to offer each and every coin and value you hold still means you owe that. It's not possible because the wallet already is not online anymore? Doesn't matter also since you still hold the coins. If you sold them then you owe the bitcoins. If you claim you destroyed them then, well, accounting would not be the best in c-cex. And it would have been your private company pleasure to kill values that you could have easily backed up. So that possibility would be the worst explaination. What else? The amount of work? Not really, installing a normal wallet is not much different than installing a wallet on a server. And your devs are quite experienced with it already. Accounting about who owns what? Logs are still intact, manual payout can happen. At the end it doesn't matter if you think 2 weeks are enough before someone should lose his value that he trusted you with. What counts is that you were trusted with it and that you owe it. It's pretty simple. I still hope that you can see the problem. Which is a serious one.

Please ALWAYS contact me through bitcointalk pm before sending someone coins.

Regarding broken blockchains.
Unfortunately we have many of them by now and looks like it's systematic problem which affect coin developers. Here is all information we have about this problem.
1. How we register deposits? We scan for incoming transactions and check if it has enough confirmations (set by coin developer as secure for each coin we have). After we have enough confirmation the deposit get posted to user balance.
2. What makes us consider coin blockchain broken? We verify already posted deposits which already had enough confirmations and find them invalid (they have confirmations: -1 or confirmations: 0). We verify those transactions in block explorer and find them there infact giving us strong evidence of broken blockchain because usually for good working blockchains it is impossible to see invalidated transactions in block explorer or addresses with negative balance.
3. How it happens? Here we can only make an assumption. Possibly blockchain cracker put big hashpower on blockchain he attack and make instant fork, creating fake transactions and pushing confirmations to it visible for all network including our wallet. After he remove hashpower network recovers and shows those transactions invalid with negative balances on addresses realted to it. During the time of confirmed fraud transactions attacker sell coins on market and withdraw BTC without delay. After network recover attacker may also withdraw good coins from our wallet in normal way because he has them on his balance from fraud deposits. In result attackers account has no BTC or attacked coins on balance and in most cases making our wallet empty which stops us from ability to provide withdrawals.
4. How we can protect our customers from this type of attack? Infact we can't. As most of blockchain has small block time it is impossible to detect fraud transactions fast because they looks like exactly as non-fraud for all network including our wallet and they have real confirmations with real blocks visible to all.
5. What can we advise to our traders? Please, always make your own research before trading any coin. We never vouch for any dev or coin owner. When you trade coin - you trust not only exchange but mostly coin developer. If you unsure about developer or quality of coin - do not trade that coin.
6. What should coin developers care to protect their coins from this kind of attack? First - they do not have copy paste code which has being used for 1000 times already without revision and deep understanding how cryptowallet and blockchain works. They have to care much about blockchain security with checkpoints, private nodes, monitoring servers etc.
We have nothing to do with broken blockchain unless developer offer some solution. Usually they fix wallet vulnerabilities and make swap or move to more reliable blockchains like ethereum, nxt or bitcoin.
It's very nice that you have a statement regarding broken blockchain. Just one question. VTA was removed from your exchange due broken blockchain. Then community helps you to open deposits to make a swap. Later coin was removed due lack of interest and there was not contributions in coin source. Problem still exist. So why you listed again coin with broken blockchain?

I think unless you have a plan for VTA as to a roadmap or if you are taking control of the coin.Selling it after you delisted for reasons you said blockchain was broken did you fix it before relisting it. It could be considered as fraud and i am in talks with cryptocompare.com to may they interveiw your exchange site.

The most interesting thing it's when other exchanges chose to continue partnership. C-cex asked money for listing XVP and then relisted VTA with broken blockchain.

Unfortunately. LEO dev's are in touch with us all the time. And they aware about this problem. We gave them all possible technical details but they never released fixed version. Their wallet just stop to respond on RPC several minutes after start.

Thats what I said, they only care about MONEY instead of customers security. The worst is, they are also accepting listing fees from OBVIOUS Scam coins. We already stop trading in ccex much better to be safe than sorry.

If you are getting logout that is most probably because you have dynamic IP address which is changing. Other reason - you or someone else logging in from other IP.

We upgraded our Ethereum deposit routines and new we are able to set minimum Ethereum deposit amount to 0.1 ETH. Before that it was 1 ETH. You can send any Ethereum or Ethereum classic deposits starting from 0.1 ETH. Deposits lower than 0.1 will not be posted and if you send lower than 0.1 ETH - they will be lost.
