An investment is not a donation to your idea or cause.

If you "need money to make it big" you can bootstrap, take donations, or look for investors.

It's easier to raise investment than donations, because an investor expects a return in an economic/probabalistic sense(not hopes for a return)

You can't have your cake and eat it too though; once you accept investment you can't cry foul when they don't sit back and act like a donor.
