Hello AmarO, thanks for being less rude, we can have a normal conversation about it

My name is Frank Bonnet, I'm one of the Solidity developers working on the project.
First of all, nobody is forcing you to be part of this ICO. In fact, personally I prefer that the people who join DCORP (through the ICO) believe in the project as much as we do. 49% of the investment is not lost, it is used to develop DCORP and to develop a complete decentralized derivatives exchange (a unique on-blockchain platform to trade decentralized option and future contracts). Derivatives play a huge role in the traditional world and will enable users of cryptocurrencies to hedge their risks and allow leverage trading, all trustless and on the Ethereum network. Derivatives can even bring a much larger audience to the blockchain. The derivatives exchange is owned by DCORP (and thus by its shareholders) and generates Ether for them through collecting fees from premiums. Building such a platform in a new environment with limited resources is a huge undertaking and comes with huge responsibilities you can imagine.
Now, the remaining 51% of the Ether allows the token holders to decide which projects we should develop next or it allows new talent to join the organization. Voting on the development of the derivatives exchange is unnecessary, because during the ICO you can already decide if you join or not. It also serves the purpose of backing the value of DRP, the remaining Ether and the prospect of dividend and growth.
I don't see how I (we) could dump coins on the market after cashing out those projects. Can you explain please?
I hope I've answered the rest of your questions.
Is Derivatives exchange ready to go? Or will need several months to develop? I see, then investors vote on projects for your team to develop and how will those projects profit investors?
