How much does it cost to buy a listing on Bittrex?
You are right, I'm going to update the OP in a few. Thank you for making me point out and apologize for the delay.
About Bittrex: the policy to be listed there is changed. It is no longer enough pay, but (from a mail that I receipt from Ryan)...
"we only add coins under active development with high community demand. We gauge demand based off of tweets, hash power, length of bitcointalk thread, volume on other exchanges, etc. Follow us on twitter @bittrexexchange and tweet about how much you like this coin and Bittrex. We respond to creative and insightful posts to help market your favorite coins and Bittrex. I'd also consider coming to our irc channel #bittrex on irc.freenode.net and do some guerrilla marketing. The traders there can help you gain exposure for your coin."
Good distribution can be done through https://theviralexchange.com/. This will allow for the coins CREA to distribute on social networks information about the project. The very fact of the presence on TVE will be an excellent advertising project
