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

Hello!

Please, check your withdrawal transaction ID's with block explorer first. Withdrawal transaction ID can be found on your history page: https://c-cex.com/?id=h , Block explorer link can be found on main trading interface in coin info box (top right). In case you don't see your transaction in block explorer - please, reopen this ticket so we will investigate further.
Have a good day! Let us know if there is anything else we can help you with.

Thanks!

PoS blockchain needs a lot of transactions. If PoS blockchain lacks transactions take coins for payment of fees as from a random transaction. Maybe this is happened. It's not my fault. Who will cover my lost 3000 LEO and when i will get my coins from your exchange?
t******o 2017-01-17 16:40:40

You must rescan your LEOcoin daemon wallet to get my 3000 LEOcoins back. Command: lecoind -rescan
t******o 2017-01-18 21:00:59

When can I expect my LEOcoin withdraw?
