"As investor, I do not know how much am I paying for what percent of the tokens. It is blind investment".
This is not quite correct. You will always have the same percent.
The tokens will be minted up to 100,000,000. Based on the results of the public sale, at the end of the ICO, a proportional amount of tokens will be minted for the Company and the Platform to keep the balance and prevent dilution. Therefore, the community will always own 55%, the Company will own 35% and the Platform will own 10% from all minted tokens.

https://www.sether.io/for-investorsIt is correct. You think in terms of the community versus the company, whereas you should be thinking of each of your investors. I don´t know what percent of the company I get for 1 ether, because it depends on the total contribution. It is blind.
The value proposition I would like to have is: "We are selling 1.000.000 tokens. 1 ETH is X tokens, there is a soft cap of 500.000 because that is the minimum for the project. If there are tokens not sold, will be burned or distributed pro-rata to investors. All tokens will be sold at a the same price (or 10% discuount at most)".
Anything else is adding risk to something that is already risky. There is no need to reinvent the wheel.
