Let's put it this way: No other project has harmed the placement of the token on major exchanges. Many large investors are engaged in trading only on these exchanges. And the presence there allows you to attract large investments in Greentoken.
Large investments can be attracted at the stage of private sales or ICO. The fact that the token is traded on a large exchange helps to earn primarily investors.
And the developers of the project do not leave themselves some number of tokens? Of course they do. If necessary, in additional funds, they can sell part of their tokens provided a good price on the exchange.
