"The Commodity Ad Network (CDX) is the TRUTH media's counter to GOOGLE's fascist tactics! The mission of CDX is to pair up the correct content creators with the correct advertisers in an ad network that charges advertisers less and pays out to content creators more than any other large ad network. As the network grows, the value will RISE."
I Think this is a very good opportunity. If you get the token during the pre-sale you can get them cheap with the 100% bonus, i.e. 1 ETH = 3,000 CDX
The pre-sale period starts on August 26, 2017 at 2 PM UTC. It will last 120 hours (until 2 PM UTC on August 31, 2017) or until all available CDX tokens are sold, whichever event occurs first.
The ICO period starts on September 9, 2017 at 2 PM UTC. It will last 504 hours (until 2 PM UTC on September 30, 2017) or until all available CDX tokens are sold, whichever event occurs first. If all available tokens are sold in the pre-sale, then there will be no ICO.
