Slick interface, good customer support, strong KYC
I've been using Hodlnaut for several months and so far my experience with them has been great. They have very competitive rates on stable coins. Their website and mobile app are well designed and easy to navigate. I have only had one delayed withdrawal which I was compensated for. My only complaint is they really need to create an API for integration with tax software or allow you to generate a .csv that is easily imported by that software. I know they are working on this though.
