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?
In principle, listing is not necessary since TMV can be exchanged for ETH and already ETH you can exchange anywhere. This is one of the most popular cryptocurrencies in the world.
