Coinsale is decentralized IDO platform. Coinsale is a strong solution partner for cryptocurrency projects to sell tokens, increase liquidity, and reach new investors. Coinsale allows you to invest in projects at IDO events that will be held on its platform by staking its own token. Thanks to this platform which provides the opportunity to invest first, you will be one of the first investors of the projects. It serves to solve the problems created by many similar platforms, to minimize the costs of participation in IDO events and to reach larger audiences. While some platforms do not guarantee you to invest in projects even though you stake their own token, Coinsale, on the contrary aims to ensure that all stakers participate in IDO events without any problems. There are absolutely no bot systems on the Coinsale platform and this is not tolerated. It is ensured that all investors and platform users participate in IDO sales without any problems.

Coinsale.setFeePercentage(uint8) (#297-302) contains a tautology or contradiction:
- require(bool,string)(feePercentage_ >= 0,Coinsale: transaction fee percentage equals 0) (#299)
Fix the incorrect comparison by changing the value type or the comparison.
