HT is indeed at a high level: a wide range of offerings, low fees for traders (especially for liquidity providers), high volume and liquidity of the exchange itself, as well as support for leverage and derivatives, and so on. However, the exchange imposes a number of restrictions due to KYC. I'm not against verification, but I would like to receive something in return. Going through identification on an American exchange regulated by FinCEN is one thing, but working with yet another offshore entity is quite another. They are unwilling to cooperate with responsible regulatory bodies, yet they demand documents. Additionally, the translation of the interface leaves much to be desired.
