I'm still on the fence. Is it possible for Incent to exceed Waves in value?
Another question; say I buy 1 Btc worth of Incent which will get me 10,000 units now. Will the number of units I own decrease by the end of the ICO?
Absolutely. Incent is a service on top of Waves and, once the decentralized exchange is live, will be traded against any other currency which is issued on Waves in the form of a token. Theoretically, Incent could be worth double as much as Waves.
The beauty is, the bigger Incent grows, the more Waves profits from it due to having more transactions on the platform. It's a win-win situation for both projects.
To your last point: No, we are not selling proportional stakes of a fixed supply. What you see in your ICO dashboard will stay there. You can only make it increase

Why i remember sig bounty is 300k incent? But where I saw it os 1% of ico coin is bounty, 40% of that 1% is sig bounty.
You maybe have calculated a maximum of 200k Incent for the social media bounty, but never was it posted that there will be 300k for the sig campaign. As you said, it is 40% of the total bounty pool which is equal to 1% of sold tokens.
Thank you for the prompt reply. This seems very appealing.
Looks like I'll be investing in this as well.
