I'm one of the Idax users and ever since I never faced any such issues on it. Though, I submitted kyc on IDAX and so far so good.
Actually, I've been doing day trade on IDAX and it gave honestly a good profit every week, so if that is true I know Idax can fix for sure.
You know here in this field of business in crypto there are full of negative feedback. And besides, in every exchange we always do it in our own
risk.
