More investors mean more coins in circulation means less vulnerable for price manipulation.
This I understand and agree. More coins = more stability.

...the more community members we reach in this extended period the more secure will our system be...
Sorry, but not so. Security is only dependent on the dev team. Some contributors may be recruited from the community, but it's hard to sell this as a base for the extension.

Nevertheless, thanks for the comment. I do think that Corion is an interesting project and the reason I report on it is because I think it is going to be successful.
