You have absolutely no clue what you are talking about.
You are talking about ICNX. ICNP CAN invest into Chronobank. They would announce that after ICO is over. Chronobank and ICNX have nothing to do with each other.
If Iconomi want to invest they may have already invested. As they won't want to waste the 30% bonus.
ICNX too can have chronobank. If it becomes an eligible currency after few months, it can be added to ICNX .
