It is very important that listing of tokens will be on big exchange with good liquidity that price of the tokens will be good and volumes of trade will be big.
What does a good price mean? If exchange list a token that is not in demand, the good price of that token will be 0. The team should take care of the demand of their asset, but not the listing in the first place.
For me the good price is the price that is higher then the nominal price that it was during token sale.
