Using auto bidder or non-auto bidder depends on your strategy and the amount of
T-Credits you have.
If you want to be conservative with your bids, do not use the auto-bidder.
using auto-bidder will use up all your T-credits fast if you run into
an aggressive bidder.
The best way to win an auction using both bidders is to set a goal on who you want
to bid against and how many T-credits you want to use.
