During an auction crowdloan for propsective parachain, does the auction run automatically? Or do we need to manually make a bid?

If it is manual then why doesn’t everyone go all in at the beginning of the auction period?

Adding to William's answer, here is an example that shows the bidding in action. When a campaign receives a contribution, the bid is automatically placed with the updated balance. In the screenshot below, you can see the block numbers at which bids have been automatically placed due to crowdloan contributions

A crowdloan automatically places a bid in the on_initialize hook (e.g. every block) after entering the ending period if the raised funds have increased since the last bid, see here.
