по мне так децентральность контролируется страхом. Вот прикинь, у чела,s денег в битках ... Гейтс младенцем покажется.... а ты тут давай сегвит, вилка, общество само решит... АГА . Если и будет сегвит, то под контролем. Не можешь - отменяй, а то голова будет болеть и ты не узнаешь. А мы имели хомяков и будем иметь. Золотое правило- где безумные деньги, там маф и я.

Please note! Bitcoin gold (BTG) are preserved at all and in full volume on all exchanges on which it previously traded. And access to trading and coins is opened. And the blockchain not broken (as You unsubscribe). You need to investigate and try to adequately get out of the situation. We think that a group of creators led by architect Jack Liao can and should evaluate the actions of C-CEX. From a favourable decision may depend on the demand for BTG and as a consequence cost. Ready to provide all possible details and photographs on our work in this exchange. Sure will join us brokers who are under such action of the exchange C-CEX.

WOW! Exchange since March continues to host and KNOW about the broken blockchain coins "Bitcoin gold", but trading BTG continues to 20.10.2017. WHAT IS THAT EXCHANGE?
? Appeal to the creators of the Bitcoin Gold! Did you know that the exchange platform", C-CEX" about 75 hours ago with no warning blocked the auction and the balance Bitcoin Gold (BTG). Received by the brokers during trading BTG locked and, judging by the letters of support will not be unlocked. As they said, That's your problem, and we are not responsible for your actions. Support
Hello!
Blockchain of this coin is broken. It has unconfirmed transactions which appeared to be confirmed before. Those transactions are result of successful double spend attack on blockchain which brought many user balances including our exchange balance to incorrect values. We have to remove coin from exchange because there is no way to fix this issue from our side.
Please, note - C-CEX exchange is completely fine. User balances was not compromised on C-CEX. The reason is only broken blockchain which does not have coins anymore. Please, note - when you trade coins, you trust not ony an exchange - you also trust developer who made this coin. In this case wallet had weaknesses which led to blockchain inconsistency. By this move we also saved bitcoins of our traders who had their buy orders opened. If you have opened buy orders - you can cancel them here: https://c-cex.com/?id=orders
You may also read our Rules which you agree on registration. Here is more info about broken blockchains: https://bitcointalk.org/index.php?topic=418700.msg18367923#msg18367923 We do not cover any loss inflicted by broken blockchains. This is complete information about this issue with this coin.
We already let developer know about this issue and he is avare about it. He did not provide solution yet.
Please, do not create other tickets about this issue because most probably you will have same answer.

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.
