Ok I will share my opinion:
Regarding the first point, I do not see any advantage of using KCS instead of KUS for the Launchpad.
I know that one of the reasons for using KCS, is try to avoid massive sales of KUS after the IFOs that could impact in KUS price but:
- currently the volumen of the IFOs is not so high ( vixens IFO 4400 KCS - 88000 KUS)
- The volumen collected by the IFO could be swap to different tokens not only KCS (usdt, eth, BTC) in this way the impact of the sale could be spread across different pools.
- Additionally, users would need to by KUS before the IFO.
So, my opinion is that KUS token shall be used in all the functionalities of the DEX in order to enhance the utility of the token.
Other option is follow other DEXs mechanisms, and use any kind of LP token (for example KUS-KCS) and use the KUS collected for the burning process
This last option is close related to my second question. Why not define a fee in KUS for IFOs, and use the KUS collected for burning?
The use of LP token is similar to define a fee of 100% for the farming process. 100% seems to be high, but for example 10-20% of fee I do not fell that could impact on the IFO distribution process.
