I didn't say nobody. I said "nobody in his right mind and understanding anything about investment". I'm sure there are many people happy to sign something like this. Did you make an online offer or fill in and send in this contract?
Online, I would buy in Ethereum.
Anyway, even if you make the offer in dollars, this is more or less like a future contract. If you're interested you sign it and reserve your Petros. Or you can also wait to get more details, until mid March when the pre-sale ends.
