On Hitbtc exchange, there are problem with 2fa which Isn't working several time due to poor security. I also experienced they taking long for kyc approval amd verify account. As well as fade up with their wallet maintenance issue most of the time. i have used many exchange but never ever experienced transaction fee as high as hitbtc ask. Hitbtc exchange suppose to be created for millionaires only.
i have problem with my login to hitbtc account and email to support but there is no feedback from their team at all. this is the lastest i am using hitbtc and prefer to move my assets to another exchanges, or maybe using decentralized exchanges if my token listed there. beside withdrawl fee, it has minimum trading so we could not sell all our assets. atleast 10 or its multiple must left in exchange,so we if have 10 or even more assets i am believe its equal 20$ that could not traded.
