Sorry, the problem is not the exchange, because you can change the pair by request of each founder, our problem is that our protocol is based on the Ethereum network, since we are an ERC-20 token, as you can see in:https://etherscan.io/address/0xcfd6ae8bf13f42de14867351eaff7a8a3b9fbbe7#readContract
What makes the symbol of the token generated from the creation of it, therefore it is impossible to change the symbol, the only way is to eliminate the token, and can not because it is distributed, as you can see the thread of our It is older [/url]https://bitcointalk.org/index.php?topic=2210037.0[url], and since that date the SNG symbol has been promoted, also the two projects hurt us in the markets. I think it is easier for you to add one more letter to your symbol, since you are a different protocol.

We appreciate your consideration, and attention.
