You want your token to get listed in exchanges? You'd obviously want your ERC-20 token to get listed on major exchanges like say hitbtc,Bittrex and the like. Here's what it costs,minimum of 5-10 BTC per listing. For minor exchanges like cryptopia ,you need to pay between 2-5 BTC per listing. Exchanges like etherdelta list anything on their own for free(I guess) ,without even consulting the concerned ICO team.
We are aware of the price and its OK.
The token is listed on hitbtc
