A. You can wait until the launch and probably get Emu for the a decent price or perhaps the same price as early investors. So you can just wait until you see first hand all the features.
Now this I agree with. If, after the whitepaper is published and the exchange is written,implemented and tested, you don't mind the centralised nature of emunie, nor the hatcher-tax (50%), then this would be a good time to think about investing as you would then be making an informed decision.
Until then, it's merely a gamble.
