Kraken right from my registration time was easy and I downloaded the app for usage. I deposited through fiat currency and starting trading with the exchange calmly. The customer support teams are always out for us, in case of any problem, you can easily message them via telegram, gmail etc. The exchange currently has about 227 tracing pairs and a very impressive trading volume, this means the exchange will going to be deeply liquid. I hope this exchange can reduce a bit from it fees it charges, I am kit pleased with the fee rate. Remember the exchange was established in 2011, in the united state of America.
