The Propersix exchange is one of the best crypto trading platform where users can exchange at a much faster transaction speed. Overall by using Propersix exchange system users can transaction more than 6000 transaction per second. It uses the latest blockchain technology. That’s why it is a more secure platform. Finally, I just recommended that propersix exchange is secured than all other exchanges.
How is Bittrex not on that list. IMO it’s the best overall exchange. Those guys are security experts formerly employed by Microsoft and Blackberry as well …stories I trust them to hold a reasonable amount of $
