I reallly liked coinex.pw... It's a shame this happened. At least they aren't giving you guys the runaround, takes a lot of balls to come out and be honest.
In the meantime, you guys should check out
ATOMIC-TRADEHere's a excerpt from an article about the site:
"Atomic-Trade is integrated with a high speed distributed cache and microsoft sql server enterprise which enables it to host a virtually unlimited user capacity. It also assures that users will have no interruption as changes and updates are made on a multi-tiered system. User capacity is virtually unlimited since servers can be deployed on demand within minutes. Having a multi tier redundant system also means changes and updates can be deployed with little or no user interruption. If a server goes offline more will spool up to take its place or scale back during times of low usage.
Security is tight on this exchange platform as it is
hack proof. The password storage system does not store passwords, instead it utilizes a unique hash key that is generated for each users password.
In addition, with this extraordinary multi-tier system the actual coin wallets, database, and trade engine are only accessible by designated servers in the same private network. Only the final tier is accessible to the internet via a secure connection. A 2fa option will also be available provided by Authy ensuring users the utmost in security."
The owner also paid a web security firm to audit the site.
Here's the report:

Really sorry for your losses. Give Atomic a chance if you are willing to trust another exchange. They are as secure as it gets.
