Morning everyone, we are updating a lot of content and design on the website the next few days then will move forward with the application for bittrex. We took all the feedback received the last 2 weeks and are Implementing the changes before the exchange application or marketing rollout. We want to ensure we create a great first impression to secure our spot
Soon CHC masternode could cost the same as EXCL masternode, but for now you can get 10 CHC masternodes for the price of one EXCL masternode.
