I have some HEAT on C-CEX.

HEAT ICO failed because team did not provide wallet in time. According to our rules we had to place buywall. There was tweet about that: https://twitter.com/CryptoCurrEncyX/status/824699136779886592
We will install HEAT wallet and will request ICO coins from HEAT developers (yes, we do not have any HEAT coins right now - they all holded by dev atm) after buywall expiration date. If everything goes fine - you will be able to withdraw your HEAT.

What do you mean our coins are holded by the dev? The coins assigned to ccex were in the genesis block so the only party that has access to them is the party that owns the private key. Devs do not have it, you are the only ones. Do not say you lost the private key to our coins! Why do you incorrectly state that HEAT devs are holding your coins while this is technically impossible?

No. We never had coins or private keys. We was never informed about any assignment or genesis block. HEAT dev promiced to develop fully NXT API compatible wallet. Once we will be able to run it - we will request them to send their HEAT tokens for C-CEX users.

I continue to tweet to you about your plans to distribute HEAT tokens...
Why is there never an answer?


Please, read our post above about heat. We use twitter to post news only. We do not use it for conversations. Please, use support ticket and we will answer any question.

Ok that is great.

Thanks for the information and now it is clear.

We have update from Swiscoin [SCN] devs. They promised to compensate balance loss because of doublespend attack.
Citate: "So we have decided to give you a shorted coins and we will swap our algorithm soon, our developers have started for swapping."
We have to wait for further news from them. Deposits / withdrawals and trading will be disabled until resolution of this issue.

C-cex could you clarify the situation regarding Heat,
What if C-cex Heat holders do not want to exchange their tokens for Btc?

In case dev provide working wallet at the moment of buywall expiration - coin will stay on exchange and you will be able to withdraw it. If not - it will be removed from exchange.

Well, there is a working  wallet with a working GENESIS block and live mainnet. There is also a nice lill Explorer where you can watch teh transactions floating around.

what else you need?

its not the fault of the HEAT community if your technical skills arnt enough to get this baby working in your environment.

Well, there is a working webwallet. Is that enough for you not to delist the coin?
We need to inform the community, otherwise, there seems to be the risk that a lot of people will lose their invested BTC, as other posts in this thread suggest.
Please provide some information, so the community can act upon it.

I also want to know what will happen with my deposit on ccex, had more than 500.000 scn in the amount of appr. 3 Btc, when scn was delisted....where is the proof of an attack, maybe ccex just doesn't want to pay, cause scn raised up?!!
I'm absolutely not ready to loose so much money and will find a solution, if I don't get back my deposit...

Sad to hear that. 0.3BTC is big amount for a little trader like me, c-cex should have solution to fix this problem. Some traders maybe didn't read ann on twitter before made deposit and now they lost their money because that mistake.

Swiscoin [SCN] trading removed because of broken blockchain.

Feb, 1 we detected many transactions like this:

https://www.scn[Suspicious link removed]/tx/9a7e04735ade198a499088438f01a7d459e4d701af910d62d7a14716b72863f0
https://www.scn[Suspicious link removed]/tx/54473ff263cdadddbc0e1c8a101e771f9f0a54b1ae172eb0441ff027f28629bd
...

What you see in this transaction is successful double spend attack on SCN blockchain. (yesterday block explorer shown no inputs for them. Now you can see there "Double spent attempt detected." text)

Those transactions was normal deposits to C-CEX which got >20 confirmations. Of course they were posted to balances and owner of those accounts was able to sell them for BTC and withdraw BTC instantly.

Of course after several hours, when attacker removed hashpower,  those transactions was invalidated and our wallet instead of several confirmations start to show them unconfirmed and coins from them are no longer was counted on our balance.

We let SCN support team aware about this issue with no delay and they ask us to wait for resolution. Recently, after several attempts to acquire  solution from them we got answer: "sorry to say but we can not help you".

We state that SCN blockchain was successfully attacked with double spend attack and SCN wallet was not designed to withstand it nor owners of this coin to detect it fast and control fraud hashpower.

As we had heavy deposits which are invalidated now - we end up with not enough coins in our SCN wallet to allow withdrawals.

It was impossible for C-CEX deposit engine to detect somehow those transactions because they looked exactly the same as legit. This issue happened because flaws in SCN wallet and blockchain design and low attention of owners to their coin blockchain.

If you have buy orders open for SCN - you can cancel them here: https://c-cex.com/?id=orders


So will the people who have bought [SCN] Swiscoin on C-Cex get a refund for what they have bought?
