Timvi Official has a 1By1 service that allows to exchange Ethereum (ETH) to Timvi (TMV) at the system's internal exchange rate. If you have your own internal exchanger does it mean that you do not need listing on the exchanges?
And will the internal exchange rate correspond to the real exchange rate of ETH and this coin? If so, then everything will be fine.
I think that it should correspond, otherwise users simply will not want to change their ETH at a lower price.
