EXMO delists Helbiz coin

August, 12. The crypto-exchange EXMO announced delisting of Helbiz coin:
EXMO Cryptocurrency Platform announces the Storiqa (STQ) and Helbiz (HBZ) tokens delisting. All the Trading operations for these pairs would be stopped on the 12 August 2019. Tokens will be delisted from EXMO on 13th of September.

The decision to stop the Trades and to exclude Storiqa (STQ) and Helbiz (HBZ) tokens from the EXMO exchange's listing is caused by the coins low liquidity and trading volume.

We have decided to delist these tokens due to the protection against the possible future massive losses for Traders.
Of course this situation surprised all investors. As investors investigated, it also surprised Helbiz team. Helbiz official answer is:
Statement from HBZ
Yesterday, after failing to reach a continued agreement with EXMO due to not reaching the expected levels of in-app HBZ purchases inside the our mobile app partners, our collaboration with EXMO was ended.

The possibility to acquire HBZ has been temporarily removed from our mobile application partners. The team is working on securing another partner to bring back the HBZ option as the Helbiz platform grows. Despite the temporary removal of Credit Card purchases It is still possible to fund and ride with the in-app wallet directly from an existing ERC-20 wallet holding HBZ. All users holding HBZ in app will be unaffected by this change.

All users who hold their funds on EXMO should withdraw their funds as soon as possible.
We apologize for the temporary inconvenience as we look to secure one large exchange partner that will be a part of the global growth as we bring back this functionality.
