A bit of a niche exchange, albeit an interesting one. If it wasn't for the lag in processing withdrawal requests. They claim to process withdrawal requests within 3 business days but it takes way too long. It eventually does get processed but they should change this practice. The trading screen doesn't auto refresh which means you'll be busy hitting the refresh button in your browser. They promised changes but very little has happened other than them switching to instant POLiPay which is very convenient for deposits up to $5000. However, even POLiPay is far from instant.
