I completed the request to add Devcoin to coinexchange.io today.
Fees
-----
There is a 4 BTC listing fee for new coin additions to the first base market. E.g., COIN/BTC.
There is an further 1 BTC for each optional additional base market listing, for example COIN/ETH market.
There is a 1 BTC fee charge for coin swap to be coordinate on CoinExchange. Failure to inform us of a swap will result in immediate delisting.
The listing fee also includes two maintenance and / or upgrades by our technicians per year. Any additional maintenance or upgrades will incur a 0.5 BTC each.
