Dear gvozdik,
Potential does not mean we are actually hacked but we like to inform everyone about the possibility. In The Netherlands we are in need to report any unautorized access with customer data, there is a law for this.
No user funds has been stolen and everyone can deposit or withdraw at any time.
Seems litebit is a promising exchange, will have a try on this .Everyone give it a chance, it will grow into a giant like bittrex.
