Everyone, please withdraw everything from Novaexchange - Everything!

Also DO NOT send any coins here! I repeat DO NOT!

ALL TRADES HAS BEEN STOPPED, ANY DEPOSITS WILL NOT BE ACCEPTED! WITHDRAW YOUR COINS NOW!

An vulnerability has opened up for a specific user give themselves an insane amount of Bitcoins. These has been used to trade in the markets, balances has been re-arranged.


All in all, BTC, DOGE and ESP balances cannot be trusted, the vulnerability caused the attacker insert a transaction within deposit systems. But did not think that Novaexchange is a young exchange that doesn't bank a lot of coins. The total volume of BTC in the most important wallet was 3.82 BTC before the attack, not a huge amount but that does not mean it is not painful for some.

The attacker themselves did not get away with anything - actually it is happy users that got traded in ESP market during the last few hours that became happy they sold for BTC and withdrew everything. Which caused the wallet to go empty.

All trades and such is logged and I could technically do a rollback of all trades even if it will take a lot of time to sort everything out. Which would you prefer?
I am concidering to close down the exchange permanently once you have withdrawn your coins, unless the community gives any reason for Novaexchange to stay around. I wanted the site to become a serious player in this business with a lot of alt-coins that other exchanges refuses to trade, that was the idea behind Novaexchange.

How about my 2 withdrawals of total 1.04btc?
they are in state delayed.

Edit: also i see you are trusted and this issue was not your fault, i would say that don't shut down novaexchange, but continue with better security.

Attention;

Withdraw all your available coins from Novaexchange right away! ALL COINS!

Turn of any automatic deposits.

"for a few hours"

If no updates after a few hours, this won't be looking good

They said they take down the server for investigations.

I sure hope they don't turn out to be a scam, I have some alt coins in there. I was just waiting for a price increase and now I got nothing.

I got withdraw LTC from admin wallet a while ago, hacker cannot get access to wallets
I feel sorry about everyone loses

Consider it as a lesson

Seeing https://bitcointalk.org/index.php?topic=1434700.3620
it seems they might even be hacked

DAMN,I have a lot of BTC in nova !

nova exchange is down now.

scam is over

hi , why now nova can not be opened ?

you are right , it is huge amount and I thing there is something wrong there , it is now 92 BTC , implausible number , I hope the dev will be here and explain what happened to us , on yobit untill now the trading volume didn't reach even 1 BTC , how can we believe that number on Nova .

72 BTC volume trading ESP on nova today, thats huge for this exchange
so have a question

Do anyone withdraw bitcoins from nova past 1 hour?

It is a project on going, the dev has given me api documentation, but still need to build the whole function. Once done it will be launched.

Raiblocks is a good addition. You can get a lot of traders there. Already the coin has got lot of supporters. IMO, raiblocks will trade at good volumes for 2 + years.

Hi! Will you add raiblocks in your exhange? I will help the traders in here https://bitcointalksearch.org/topic/raiblocks-raiblocks-trading-thread-1422828 if they have their own exhange site. It prevents scam. Also a promotion or some kind of advertising will help your exchange to gain more user. It's nice that you guys are adding new coins that doesn't have exchange sites yet, the only problem is your exchange site is not so lively.

Well, I prefer you to do not charge until a year or so, until you have lot of traders. Once you turn into a good exchange, pick coins selectively.

Hi,

I currently do not ask anything to list a coin, this may however change in a near future to get priority in the queue because of the amount of requests, the queue has over 28 coins right now that is in line to be added.

I prefer not to add more than maybe 1-2 coins per day to make sure they are compatible and works with the exchange RPC engine.

How much do you ask to list a coin? Do you list a coin for free? Do you host ICOs?

Thanks for adding pakcoin
