It's a better case than twitter though. There is no obvious way of monetizing twitter, while there are many ways that I can think of that snapchat can monetized. For example, Line and Kakao have massively succeeded with their sticker/character business, and snapchat could bring something similar. There are many other ways I can list. So, the issue is not "What are possible methods of monetization?" but "How do I optimize profit?" This is definitely a more favorable setting than twitter.
