There are 3 coins using the ticker symbol ACC.
Accelerator Network (ACC), AdCoin (ACC) and ACChain (ACC).
Each of them is listed on 2 different exchanges (6 in total).
If Accelerator Network (ACC) wants to get listed on CoinExchange, it can't do that under the ticker ACC since AdCoin (ACC) is already listed there.
