I also funded my account $100 (opened on Sunday) and the miles already posted today with no trade.
I think I may do a single trade for $15 total or so and then redeposit the rest of my money. Even if it were just 2500 miles I'd still do that, and the fact that it's a hit is a great deal.
Add in the fact that the basic account has no monthly fees and this is a great and easy hit.
