They scammed me of compounding 4 weeks of BTX airdrops... A lot of money back then.

Just avoid them.

I used this exchange before when I was joining the signature campaign in Byteball, a time comes that I want to trade my reward coins into this exchange to BTC so, I decided to deposit my Byteball on this exchange. Luckily at that time, my transaction was going smooth but after days passed I had read here in section a different complained that they hold the deposited coin on their exchange. After that, I transfer into other exchange.
Yes, you're right this thread is enough to convince people to avoid the possible problems because they had different issues I have heard on this exchange better to stay away to avoid a serious problem in the future.

Just to know:
Is there anyone with a problem with his deposits not credited? 2 months for wallet maintenance and deposits during this time are wasted.
I didn't follow the news since few days and currently not in a good moon.

I didn't try to deposit anything since. My balance was showing my missing coins the next day I posted my previous message. I waited two months for a wallet in maintenance. They fixed it but in fact, I think we couldn't credit our balance, at least the site would have displayed our balance at zero. I will refrain to use cryptopia as I used before.

edit: I tried and it worked.

Latest news - Cryptopia exchange $2.5 million loss: Etherdelta hacker strikes again



New year, new hack. We’re just fifteen days into 2019 and already a crypto exchange has been hacked. New Zealand exchange Cryptopia lost significant funds in a security breach on January 13 (UTC), according to a statement. By examining blockchain records (Cryptopia didn’t disclose how much was stolen), it appears that 20,000 ETH ($2.5 million) has been stolen by none other than the hacker or hackers behind the 2017 Etherdelta attack. (We’ve reached out to Cryptopia for comment, but the company has not responded to our questions at the time we went to press.)

Since the hack, Cryptopia underwent unexpected maintenance–and has yet to resume normal service. The exchange has notified government exchanges including the New Zealand police and the High Tech Crimes Unit. In response, some community members have accused the exchange of running an exit scam. However, there is no evidence this was the case.

In fact, when examining blockchain records, it may have been the same hacker that stole tens of thousands of dollars worth of ETH back in 2017 by lifting private keys from decentralized exchange Etherdelta. Some ETH from the source of funds used for the Etherdelta attack was sent to the same address as a likely recipient of the Cryptopia hack. And it’s a rather suspicious address indeed...

Hi Guys, I've got a thread over yonder: Cryptopia - ONLINE ARTICLES related to hack & theft of funds 2019 - https://bt.irlbtc.com/view/5097916.0 where I'm trying to track all online news articles about the hack and theft of funds (as well as links to all other Cryptopia related threads) and am trying to compile a list of funds stolen and track where they have ended up.  If you can provide any links I'd appreciate it (It's not a discussion thread as such, the main Cryptopia thread is here: Cryptopia Cryptocurrency Platform Services and Development. Thanks for reading.

Decentralized exchange = no admins no 3rd party.
The funds are in your pocket, they only leave your pocket to go in the pocket of a seller/buyer at the time of the exchange through a smart contract.

No one can do anything to block decentralized exchanges.
And this is the main reason they are developed, so no government, no bank can shut them down. 

Hard to say - the New Zealand Police investigation is taking its course and they haven't posted any updates on their website for a while now.
