If it was just about paying to get listed, NVST would have already been listed in different exchanges. It is not about the fact of been listed, it is about the quality, the volume, the reputation, all these aspects have to be taken in count in order to provide the best access possible and a good protection agains manipulations. Even if exchanges like bittrex and poloniex doesn't really offers a protection against pump&dump, they are widely used which is a good counter weight.
Hello.
I have to inform you that this 2 are US based exchanges and they lately introduced some shitty
withdrawal policies and limits.
They also ask people to identify.
Also poloniex grew faster that it can sustain now i see lot of people complaining about their support.
They need weeks to solve simple problems and to answer to a submitted ticket.
DO not waste time with exchanges.
Is better that you focus your time and resources on the NVO development.
PEOPLE you loose control over your funds if you deposit on a centralized exchange.
They become owners of your BTC, LTC ....
They can impose silly policies and block your withdrawals.
