Noticed, there is minimum payment tag. Please verify if this is correct: you can send only transactsions that exceeds amount of minimum sum indicated.

But what will happen if smb sends required amount in batches or will just send smaller ammount, will funds will be returned?

Minimum Investment ?

If to invest with different crypto (for example ETH) - exchange rate to BTC will be in moment of transaction or will counted at the end of ICO?

In the moment of transaction.

Certainly looks like one worth investing in

How can one profit from this?? By selling the tokens only or how else?

That is essentially correct. From our FAQ: https://chronobank.io/faq

No tracking of "total invested so far" on the ico dashboard? So those of us interested can follow how popular the project is?

Wow. Good solid early investment. Looks to be on track to have a great first day! Glad to be onboard.
