I was thinking about 80% profit sharing.
Because i've read that,
but in fact :
Appendix A - Profit sharing
Amount raised VS Profit Share
The amount of gross profit ETHbits will share is dependent on how much is raised during the Crowdsale. For every 1000 ETHER raised over minimum funding goal 10000 ETH Ethbits will share 1% of the gross profit.
Raised 10000 ETH or less - Profit (GROSS) share 10%
Raised 20000 ETH or less - Profit (GROSS) share 20%
Raised 30000 ETH or less - Profit (GROSS) share 30%
Raised 40000 ETH or less - Profit (GROSS) share 40%
This is already explained by ethbits on last pages of the thread, please read it, no matter how much will be raise on the ICO, the profit sharing will not be that affected, since the unsold coins will be burned.
