When I initially discovered the exchange I was searching for the sign up menu thinking it was an exchange that will require me filling in my informations and details before I can trade but dydx exchange was completely different and what baffles me the most was that I could also even perform most of the trading activities I had previously performed on other exchanges were I registered and performed KYC verification to trade. Despite the exchange's unique attributes I found some of it's service unimpressive, there were only few coins listed on the exchange for traders to swap and the most of it all was that the exchange doesn't support fiat to crypto trading,this is one of the features I always look out for in most virtual currency exchange although it was nice to know that the exchange offers an secured trade interface.
