That is a good point, since we are not a company and do not follow a regular company financial year we mentioned these dates has in number of months ( Q1 until April = 4 months and so on ).
A quarter is 1/4 of something. 1/4th of a year in this case, so Q1 is January-March, Q2 is April-June, Q3 is July-September and Q4 is October-December. "Q1 until April = 4 months" means that there are 16 months in a year.

Besides, the coin lives on even without investors.
someone has to pay for your work. Or are you a volunteer?
that's what premine is for.
to fund development.
How are you gonna fund development with something that is worthless?

It's the investors that make the coin alive, what good is all your premine if you can't use it for anything (can't sell for BTC, can't purchase any goods etc)?
It isn't worthless for us as we see the potential more than anyone else. We don't even look at the current price and for sure will not sell for a long while. See you in a year or so ;-)
