You're missing out on 3 main points:
- Reminder on dividends: they will indefinitely remain at 50% of revenue, while KCS will eventually drop and while BNB/Bibox are only about trading fees
- ICO platform: there has already been 4 ICOs on the platform, and more to come
- Main selling point: fiat is to be implemented in Q1 2018 (€/$ deposits/withdrawals). Kraken is also suffering a lot in terms of UI and still manages to have $500m trading volume on average. At this level, a holder of 10k COSS would make around $500 a week

So lots of room to grow. Key issue seems to be the platform and its usability, leading to the only significant trading volume being done on COSS pairs (c. 80%). A very positive thing with the COSS team is how they're listening to their stakeholders on the Telegram. They've set up yesterday a Trello with c.15 web developers helping them fix their bugs. They are hiring a front end developer next week and a back end developer in the next month or so from my understanding. This is why I'm a long term holder.
