Exchanges will become more important when the marketing campaign is underway. Marketing campaign cannot start until the wallet is released. There's a smart way to handle things and LaLa is doing that.
Yes to use money on marketing until now would be bad money to use.. Much better like you say that they do it smart and wait for the wallet to get out, and hopefully also the market can get more positive. I have seen that the worlds 9 largest stock exchange will list crypto, and when more and more big money get in crypto, hopefully it will make manipulation more difficult as the volume will be much higher..Marketing will come once they have something to market.
They marketed the ico very good so I trust them in that regard
