To profit from pump and dumps and make more bitcoins, that is what 99% of people use altcoins for lol. All that matters is king bitcoin, the rest of coins are irrelevant. Waves looks like an interesting project, but unfortunately without poloniex it's never going to pump, and no matter how good your project is, if it's not doing good price wise then it's a dead project.
Right now, at the current price of Bitcoin, Waves developers own around 20 million dollars to spend on the project, and it has just started. Full nodes have just been released, there is still the gui asset to be developed, DEX platform (descentralized exchange) and one of the most important things, the fiat gateways. And waves is an inflation less system, this means that no more tokens will be ever produced. So, the more the platform is used and the more Fiat you get into the platform, the higher the price the waves token will be worth.
Poloniex would be awesome, it would allow more users to buy into Waves tokens, but sincerely...in the long term with the fiat gateways and DEX, it is not needed and Sasha knows about that. It is just not an over night rich scheme like people want to, the platform has to gather some real use in the real world and this takes some time.
