Have used this couple of times now for crypto-crypto trading. Everything has gone well and It's fast&has low fees
I wouldn't recommend using fiat at the moment, it has insanely high fees. For example I checked earlier today when 1 litecoin was $50 that how much would it cost to buy one through them. Well the price was something like $80 for 1LTC which is very high price. So you pay $30 for extra fees.
Hey! thanks for your feedback. USD rates are depending on our bank cards processing partner. Unfortunately in some cases commission can be rather huge to cover the risks of charge backs and fraud, but verification process is super fast, unlike other exchanges. Anyway we are working on new partners integrations to offer your better rates. In case of crypto-crypto transactions we charge only 0.5% fee from the best available rate on the market!
