For traders by traders
Our company has been operating algorithmic trading in crypto currencies since 2014. With the large number of individual transactions that result from software-based trading, we were confronted with the need to automate our financial accounting at an early stage. We realized that many fellow traders – who have a hard time processing trading history – would benefit from our experience therefore, we developed COYN as an automated solution. Our close dialogue with traders makes COYN better every day.
