being able to have different application built in one e.g. taking payments and signing up customers.

It is now nearly two years ever since I implemented Kraken. Prior to this tool, I was using LocalBitcoins which was full of fraudsters. With Kraken, I am able to trade (buy and sell) bitcoins. It has an iOS mobile application which is easy to use and has clean UI interface.

Kraken provides access to the widest range of tokens and is accessible globally. Many other exchanges either do not have the range of tokens or are limited in access based on geographic scope.
