I do not know why tokens registered in MEW wallet do not have a price of $ and are not yet listed on the exchange. but why can this token be traded on several exchanges?
isn't the token that can be traded only a token that already has a price of $ and already has an exchange to trade it?
Most of these exchanges has not entered an exchange and so cannot be traded, but the token will surely be in the wallet because it was built on Ethereum smart contract and the only way to distribute it is that. When the token enters an exchange, it will automatically start having the dollar equivalent of it being calculated by the tool Ethereum uses in converting their token value to USD.
I have so many of them in my portfolio that I have even been holding for a very long time now, and I am beginning to wonder too if those tokens will ever enter an exchange. I believe that with time, some of these token will surely enter an exchange, I dint know what is delaying them though, but I want to believe that they are just waiting for the altcoins season for them to increase in value.
