Before contacting support, you can ask about your issue in chat. English chat always has users online.
For account restore use that page - Restore
For partnership and technical issues you can use direct emails to firstname.lastname@example.org (General support)
You can use any of the 4 languages to communicate: English, Spanish, Portuguese, Russian
For adding coins you can use only page of Coin adding . Price of coin adding is non-negotiable and can't be paid in other coins. Don't write to supports about coin adding they don't take decisions about that.
if you have some error with deposits/withdrawals/pool rewards it is recommended to create a ticket.
This way support will be able to help faster and more efficient.
Be polite when talking to support and don't ask about things that don't belong to CryptoHub. Also support doesnt respond about our online-staking (PoS), if you think it works badly - just don't use it.
