Ну как мы и говорили: "у нас технические проблемы, все ваши средства в безопасности, бла-бла-бла..."
Dear trader,
Thank you for reaching out!
HitBTC is experiencing a short period of temporary downtime. Our Technical Team is aware of the issue and is already working on a solution.
Please note that all your funds are kept safe and secure, even though at the moment you cannot see them. All cryptocurrency deposits and withdrawals you have made during this time are kept in a waiting line and will be credited to your accounts after we are back.
Regards,
Nelly Marsh
HitBTC Support Team
